In Bug 479334, I updated the dictionary to include a large number of new words suggested by bug reporters, which were filed as over 25 separate bugs.

Along the lines of the "source code spelling fixes" bug, I would like to make this the consolidated bug for adding new words to the spell checker dictionary. 

From now (June 2009) until the next time the dictionary gets patched, please leave a comment in this bug with the word you would like added (and a rationale, if any).

Please also dupe bugs (with bug numbers > 5,000,000) that make dictionary suggestions to this bug.

Add testsuite and testcase

From bug 503687, add afterwards.
html in lowercase is not in the dictionary, so saying "foo.html" appears spelled wrong.

The same applies to other extensions like jpg, gif, png, css, js, php, etc.

Though these aren't very important, they would be helpful additions.

Also from my last comment, the plural forms would be needed too, "testsuites" and "testcases".
Neither "testsuite" nor "testcase" is an English word; neither should be added.

Similarly, HTML, JPG, GIF, etc. are acronyms and should properly appear in uppercase in written documents.  Users who regularly write about file names can add them to personal dictionaries if desired; for similar reasons, things like "usr" shouldn't be in the dictionary.  (FWIW, I write about file names all the time, and I've gotten along just fine with per-file whitelisting, which protects me from typos in situations where file names aren't the topic without adding significant inconvenience.)

So how should be XML written? Almost all Microsoft stuff I see "Xml". 

Real world case in the IT industry it is the standard to use "testsuite", "testcase", html, jpg, gif, url, popup, plugin etc. Many times in design document reviews I insisted usage of uppercase for COBOL, when other issues got priority my comments got ignored. So I stopped pointing out that.

Firefox/Mozilla need to know whom we are targeting as spellcheck user.
Are we targeting a person who is writing novel in Firefox?
Or people who are just using email, forum, putting comments etc on intranet/internet sites.

I can agree "usr" shouldn't be in the dictionary.
But "hmm" "um" "umm" will be good as every body use them in chat.

Alternatively we could allow use of multiple dictionary. The way WordPerfect allowed to Technical Dictionary along with English Dictionary.
(In reply to comment #8.)

The point of a spell checker is to help people who want to spell things correctly.  That doesn't mean adding misspellings simply because they are popular.  A dictionary shouldn't contain "Xml" any more than it should contain "definately", no matter how many people at Microsoft or elsewhere screw it up.

There is little harm in having a squiggly underline under a word.  But the misspelled "ophthalmic", in comment #3 above, got a person in trouble with his boss.  I believe that spelling dictionaries are setting a standard and thus should be conservative.

Personal dictionaries and multiple dictionaries have advantages (and disadvantages), but that should go in a different bug report.

Some words to start the next patch: 

* Dieing
I would vote (strongly) against "exacta".  As a general rule, it's not a good idea to insert words that are rarely used and are a small typo away from a common word.  The other three are OK, since they aren't close to common words, although horse-race betting is sufficiently specialized that it wouldn't break my heart to see them omitted.
Geoff, thanks for the suggestion. "exacta" occurs on over 2 million English web pages, which is a lot relative to many of our dictionary words (although "exact" occurs on around 500 million). 

So it depends on what we're trying to do -- prevent false positive "spelling errors" of "exacta," or prevent false negative misspellings of "exact." We should think about it more when preparing the next patch.

"trifecta," however, is part of ordinary language and should definitely be included.
To deal with words like "exacta" the best solution would be to make the spell checker more intelligent. It could do some basic grammar checking to spot that kind of thing.

For the moment I think exacta should be included. Adding an extra 'a' to the end of a "exact" does not seem very likely to happen. The 'a' key is far from the 't' key and the word "a" never follows "exact". If the following word started with 'a' and the user presses the space bar after it rather than before then the next word will be misspelt and the error should come to light.
I'll point out the following, even though my preference is for the spell checker to be a superset of commonly accepted dictionaries (dictionary words + common "web words"). So although I agree with's conclusion (that we should keep exacta), "exacts" is an English word that could easily be "typo'ed" to "exacta," since "s" and "a" are adjacent.
I suppose you have to ask what the spelling checker is for. To my mind it's sole purpose is to detect misspelt words. Detecting the wrong word is up to grammar checking.

I think the debate over "exacta" is a bit of a red herring for that reason. The spelling checker does not proof-read the text. Even typos are outside of it's core functionality IMHO.
Thanks for the thoughtful comments, James and Paul. 

Let's try to keep this bug for word additions/deletions, not a place to debate spell checker policy. If you feel very strongly about some such issue, please open another bug in the spell check component.
Paul, I can assure you (based on over 20 years of experience in spell checking) that adding an extra "a" is quite common for a number of reasons.  Typos come from more than just hitting adjacent keys.

The best solution for this sort of problem is the private dictionary.  People who regularly type a word can add it, while people who don't won't be bothered by false positives.  I presume Mozilla supports a private dictionary?

As to grammar checking, I wish.
Bug 153104 has a list of country names. Some are still not in the dictionary:

Darussalam (in Brunei Darussalam)
Bouvet (in Bouvet Island)
Malvinas (in Falkland Islands)
Faroe (in Faroe Islands)
Sri Lanka
Miquelon (in Saint Pierre and Miquelon)
Mayen (in Svalbard and Jan Mayen)
Sao (in Sao Tome and Principe)
Futuna (in Wallis and Futuna)
Sao also appears in a lot of city names (e.g., Sao Paolo, Brazil).

My only question is about Darussalam.  Since this is a transliteration from the Arabic, is there a standard spelling?  (I don't know; I'm asking.  I've seen "Dar-es-Salaam" and am wondering if it's a different transliteration of the same word.)

commenters (plural) not allowed in Minefield/3.7a1pre.

I don't know if 
can be tweaked to allow "commenters"; it seems other words have a separate "-er" form that handles the plural noun (e.g. kill/JMDRSZG + killer/M).
Thanks for that one. We should keep affixes as simple and consistent across the dictionary as possible, so commenter/MS is best.
The "Z" flag will add "ers" to a word.  So comment/GSMDRZ will handle the plural (but not "commenter's" because there isn't a flag for that, though there should be).

In general, though, the simplest approach is to use munchlist to generate affix flags.  That way, you can just add any random word form and not have to worry about affix rules (which are sometimes a bit confusing).

7 Million English language google results are enough for inclusion, I think.


Jo, there are hundreds or thousands of words in our dictionary that aren't in M-W, especially newer words or words prevalent on the internet. If you believe our policy of including words that aren't in some particular dictionary is a problem, please file another bug.
I've seen several bugs were such requests were rejected because the words could not be found in m-w (or Oxford or whatever).

Parkour has only 2.920.000 results btw, traceur 109.000. And not all of them are English anyway (eeven on the first page of the Google results), as the language is often guessed wrongly. But that doesn't matter.
I don't think the Google hit count is a good metric.  After all, there are over 8 million hits for "independant" (it hurts me to even type it!).

A better criterion is twofold: (a) do enough people use the word that it's a burden to ask them all to put it into their private dictionaries, and (b) is it likely to mask a typo of an existing word.  By that criterion, I'd argue that parkour is barely OK but traceur should be avoided, since it's rare and hides mistypings of "tracer".
Upstream Maintainer Here:

I have looked through many of the bug reports and I would roughly
classify them as falling into the following categories:

1) Common words which should probably be added, the only reason
they are not there is because of bugs in the creation process.
For example: analyses

2) New words which should probably be added.

3) Proper names which possible should be added

4) Not so common words which user X thinks should be added

5) Variant spelling of a word which are acceptable spelling, but
perhaps not very common.

As the upstream maintainer I would really like to know about (1) since
they represent a problem.  In fact I just created a release and I
would like to have known "analyses" before hand.  I would also like to
know about (2) and (3), even if I don't add every suggestion.  I do
not have time to actively monitor other projects bug reports.  The
best thing is to file bug reports at; however,
I admit that the sourceforge bug tracker can be a pain to use.  You
can also email  Just adding to the CC list would be a big
help.  If this would be possible please email me privately to work out
the details (like making sure the post gets through).

As for (4), I purposely limit the dictionary size to avoid many of the
problems Geoff Kuenning talked about.  The upstream dictionary is
generated from SCOWL ( which offers
wordlist in a variety of sizes.  I currently use the 60 size which I
think is a good compromise in including common words, while avoiding
the not-so-common words which could mask spelling mistakes.  I
can very easily generate a dictionary from a larger size.  Size 70
will include most words found in the dictionary, and if that not big
enough for you, I can include size 80.  See the SCOWL readme for
additional information.  

Another thing that could be done is to only let in words from a larger
size if they would not mask spelling mistakes.  This will take a bit
of work, but it might be worth it.  It will require some sort of
automatic check for when a word is close-enough to not warrant
inclusion.  If anyone is interested in pursuing this approach it is
perhaps best to take the discussion the the wordlist-devel mailing

Note that another problem with a large dictionary is cluttering the
suggestion list, my proposed solution above will not help here.

As for (5), this is deliberate choice.  In order to promote consistent
spelling I, for the most part, only include one spelling for a word.
However, if you want I can easily create a dictionary for you which
includes additional variants.  You have two choices:  I can include
one with just the common variants (for example, "grey" is not
included) or one which includes all variants which are considered
acceptable (including "grey").
Hi Kevin, thanks for taking a look. I'd like to discuss this with you at greater length, but one preliminary point (I think you're aware of this but want to make it explicit) is that the volume of bug reports here aren't really typical of the current Firefox dictionary patch -- they're largely the squeaky wheel getting greased (and I include many of my own additions in that group ;), and thus include a lot of (4) and (5)s in your categorization. 

I would say the patch itself is mostly (2) new words, especially from Chromium; a large set of (3) proper names, source unclear; and a fair amount of (1) omissions.

I do like the idea of selectively adding words that don't cause spelling check false negatives on high frequency words. That seems like an interesting but manageable coding challenge.
Matt, thanks for you fast reply.

Although many of the additions mentioned in comments in this bug fall in (4) and (5), many of the bugs mentioned in Bug 479334 do not, and in fact after reviewing all of them I have acted on most of them.

We should probably take any remaining discussion offline.  I encourage everyone with an interest in the English dictionary to join the wordlist-devel mailing list (, it is a very low volume list.

Dan, I'm sure we'd all LOVE to have a comprehensive word collection.  If you can point us to a source, it would be much appreciated.  But I will note, to forestall unhelpful suggestions, that copyrighted collections aren't useful, nor are definitional dictionaries like Webster's and Wiktionary always helpful, for several reasons.
How about the dictionary used in OpenOffice?  Is that not an open-source project?
The OpenOffice dictionary is what we're using right now. Currently, Firefox has a somewhat larger dictionary than OpenOffice. 

This bug is for word suggestions, not dictionary suggestions or general spellchecker complaints. 

If there are specific missing words that you're having trouble with, add them as a comment here and they will be considered for future dictionary patches.

If you have a practical proposal for a new dictionary or word source that can be correctly licensed to use with open-source software such as Firefox, open a NEW bug.

Given the post above about the choice of word lists, could I suggest offering a few choices of dictionary--say, the 60, 70 and 80 levels?
"Stormtrooper" is not a word; it's two words: storm trooper.  The correct fix is to remove "stormtroopers" from the dictionary.

It's "spell checker", not "spellchecker".  Actually, it's "spelling checker."  And "checking spelling".  Although "spell-check" has become fairly common usage.

Likewise, "realtime" isn't a word.  You should write "real time" or "real-time" depending on whether you're using it as a noun or an adjective.

"Las" is a tough one, since it can hide typos (e.g., leaving the last letter off "last").  But if it's only capitalized in the dictionary, I'd add it.
Sorry everyone that I had not seen this bug yet.

First things first, Kevin, nice to meet you!  We at Mozilla have been accepting individual word additions in other bugs for a while, and our dictionary is quite diverged from the upstream hunspell dictionary unfortunately.  It would be nice if we could revisit this at some point.  Is that something which interests you?

To others, I don't think this bug is in a very good shape to be actionable.  There is a long list of words here and it's very difficult to go through the full list and accept them into the en-US dictionary.  Does someone want to volunteer to create a comprehensive list somewhere so that we can look into adding the words on that list to our dictionary?  If yes, please get in touch with me.  I don't know if doing that work throughout the comments on this bug is going to make things very easy to handle, so we might want to do that work outside of Bugzilla to keep things maintainable.

Does the openoffice dictionary migrate into FF periodically, or is this an old version we just keep using? I ask because I wonder if the answer isn't to go upstream and add everything here to that one.

We unfortunately don't currently have a good way of receiving updates from any upstream project.  To the best of my knowledge, we got the initial word list from SCOWL some time in 2008, added some extra words that the chromium projects added to their dictionaries, added in some more Mozilla specific words, and have not received any data from either of those upstreams since then.  (Note that I was not working on this code back when the original dictionary was added.)

Since then we've been making individual small updates to the dictionary every now and then.  At some point we should get a better story for communicating these fixes back and forth with the upstream projects but that doesn't necessarily block adding the words suggested here.

Yes it is.  I very much want to avoid a another fork of the English
dictionaries.  I do not have a lot of time to devote to maintaining
the dictionary, but fortunately the English language does not change
that fast. :) David Bartlett British hunspell dictionary was an
unfortunate fork that was created primary due to a communication

I am somewhat picky about what words to I accept but I am not
unreasonable.  Suggestions are best submitted as a bug report at  But before doing so please
take the time to understand what SCOWL is (see and how the hunspell dictionary is
created from SCOWL.  In particular, note that the official hunspell
dictionary is a subset of SCOWL and it is possible to create your own
customized dictionary by choosing a different subset.  In particular
and as a matter of policy, I generally only include one spelling of a
word and also decided that fewer (up to level 60 in SCOWL) words is
better than more (level 70, or even 80) for the purpose of spell

With this in mind one huge time saver for me will be to determine if
suggestions to add are (1) already in the newest upstream version or
(2) in SCOWL but not in the subset that was used to create the
Hunspell dictionary.  (It should be easy to write a script to do this
once you understand SCOWL, but I don't have the time right now.) If
(2) is the case I may still consider it giving a compelling enough
argument.  Also, it is good to check and
see how frequently the word is used in a respectable Corpus as I do
not consider google result count a valid source without a compiling
reason.  (Also, as a super long term goal, I hope to use the Coca
corpus to create a better wordlist.)

The best way to get changes upstream is to submit requests for new words on the GitHub issue tracker.  If you find that I am not letting in enough words, I am willing to consider having a special Mozilla supplement file if it will make staying in sync easier.

I'm not sure exactly what's going on:

It definitely does not accept unreceive as a word.  However, sometimes it's accepting unreceived as a word--why the past but not the present?  Furthermore, it's being inconsistent here, sometimes flagging unreceived but accepting the incorrect unrecieved.  Of course now that I try to put it on the list I can't get it to misbehave.  (I haven't gotten it to accept unrecieve at all.)

Depends on: 1151296
"Unreceive" isn't accepted as a word because it isn't a word.  It's that simple.

"Unreceived" isn't the past tense of a verb, it's an adjective.  That's why "unreceive" and "unreceiving" aren't in the dictionary.

If somebody receives something in error, they don't "unreceive", they send it back.  If an operator marks a job as received (which is, in this case, an adjective) they don't fix the mistake by unreceiving the job, they fix it by unmarking it.

If it's not a word then why is "unreceived" accepted?

And Firefox is flagging "unmarking".
Go back and read what I wrote.  "Unreceived" with a D is a word: it's an adjective.  "Unreceive" without the D isn't a word.

And "unmark" shouldn't be in the dictionary either; I erred by using it--see, for example.  I should have said "removing the mark."

Egads - expressing surprise, anger, or affirmation. Singular is in there, plural is missing.
"webpages" isn't a word.  It's a mistake made by people who don't want to type a space in "web pages" (which should actually be "Web pages", since the WWW is a proper noun).

"egads" also is not the plural of "egad", and a quick check of authorities like Merriam-Webster suggests that "egad" is the correct usage.
AP Style Guide has website as one word and recommends lowercasing web these days, but yeah, I can't find their stance on "webpage." I'll retract that one for the moment! 

Egads is indeed not the plural per se, but it's listed as an alternative on and in Google. It's not important what's the "correct usage", provided both are in the dictionary. The spellchecher should be as broad as possible. If it's a word or word variant and it's in the dictionary, it shouldn't be flagged as a misspelling.
> APIs, plural of API.

> fundraising

listed in en_US.dic
> The spellchecher should be as broad as possible. If it's a word or word variant and it's in the dictionary, it shouldn't be flagged as a misspelling.

Actually, it's the reverse.  The whole point of spellcheckers it to help people conform to a standard.  So if there is a preferred usage, the spellchecker should encourage that preference.  Otherwise we should accept mistakes like "desparate".

There's also the issue of consistency: if a person has a habit of not always writing a word the same way, we should help them choose one of them.  That's why ispell's dictionary only accepts "totaled" even though "totalled" is considered an acceptable alternate (and I hope Mozilla's dictionary does the same). and (especially) Google are not particularly reliable authorities.  I prefer sources like OED and MW, where the editors have devoted their life to the language.

So IMHO "egads" shouldn't be there.  "Fundraising"...definitely; it's in common usage now, as is "fundraiser".  Although somewhat oddly, IMO not "fundraise" (instead, people should write "raise funds").

pruno -

an alcoholic wine-like drink made by prison inmates (1936)
I'd argue against "pruno" on the grounds that it's rarely used and would hide typos for more common words such as prune.

Of course if it's regularly used in some regions then it should be there...
> if it's regularly used in some regions then it should be there...

This is the *American* English dictionary, for gosh sakes. Pruno belongs in this dictionary.

Onwards - plural. Singular is there; plural is missing.
Also "interoperable".

I would argue against "trendline" (should be written "trend line", which is perfectly usable) and "onwards". "Onward" is an adverb, not a noun, so there is no such thing as a plural form--and the added "s" is an unnecessary colloquialism that merely encourages inconsistency.  (OTOH I'll note that the related form "backwards" is well established in English.)
