Words With Friends is a popular “Scrabble” style word game on the iOS. To judge if a word is playable or not it uses a modified version of the Enable1 word list. The WWF list has some deletions and some additions:

This is the command I used to find the lists of changed words between the versions. It only works for word lists that are reasonably close, so would probably not work for comparing SOWPODS to TWL/OWL.

diff enable1lf.txt enable1-wwf3.12.txt | sort | grep "^>.*" | cut -c 3- | tr '\n' ',' | sed s/.$// | pbcopy

Delete words are mostly profanity and racial slurs, close your eyes now if you don’t want to see.

Deleted words:

BITCHED, BITCHERIES, BITCHERY, BITCHIER, BITCHIEST, BITCHILY, BITCHINESS, BITCHINESSES, BITCHING, BITCHY, CHINK, CHINKS, CHINKY, CUM, CUNT, CUNTS, FAG, FAGGED, FAGGING, FAGGOT, FAGGOTED, FAGGOTING, FAGGOTINGS, FAGGOTRIES, FAGGOTRY, FAGGOTS, FAGGOTY, FAGGY, FAGIN, FAGINS, FAGOT, FAGOTED, FAGOTER, FAGOTERS, FAGOTING, FAGOTINGS, FAGOTS, FAGS, FUCK, FUCKED, FUCKER, FUCKERS, FUCKING, FUCKS, FUCKUP, FUCKUPS, GODDAM, GODDAMMED, GODDAMMING, GODDAMN, GODDAMNED, GODDAMNING, GODDAMNS, GODDAMS, GOOK, GOOKS, GOOKY, JEW, JEWED, JEWING, JEWS, MOTHERFUCKER, MOTHERFUCKERS, MOTHERFUCKING, NIGGER, NIGGERS, NIGGLE, NIGGLED, NIGGLER, NIGGLERS, NIGGLES, SLUT, SLUTS, SLUTTIER, SLUTTIEST, SLUTTISH, SLUTTISHLY, SLUTTISHNESS, SLUTTISHNESSES, SLUTTY, SPIC, SPICK, SPICKS, SPICS, WOG, WOGS

That’s a much briefer version of OSPD‘s removal of “offensive” words, which was a bit far reaching, removing words like MICK and FATSO, which remain in WWF. In addition, WWF have chosen to remove CUM, FAG, SLUT and BITCHY (and variants) which remain in the family friendly OSPD thanks to their alternate meanings. (But they left BITCH). They also removed NIGGLE, which has no alternate meanings, and is not even racist, but has simply been tainted by its resemblance to NIGGER.

Interestingly some of these words were allowed in earlier version of WWF. The following were removed sometime between version 3.07 and 3.12, almost certainly just because someone complained.

CHINK, CHINKS, CHINKY, GODDAM, GODDAMMED, GODDAMMING, GODDAMN, GODDAMNED, GODDAMNING, GODDAMNS, GODDAMS, GOOK, GOOKS, GOOKY, JEWING, JEWS, NIGGLE, NIGGLED, NIGGLER, NIGGLERS, NIGGLES, SPIC, SPICK, SPICKS, SPICS, WOG, WOGS

The added words are an odd bag, and I suspect it’s mostly just words that individual players have reported missing, including some very new words like VUVUZELA and GOOGLE. They have also added some words that some people might find offensive: CHODE, POO and WANK.

Note there’s a bug in the WWF list, the word JETLAG occurs twice. The second JETLAG was intended to be JETLAGS (valid in TWL), but the S was left off.

I’ve updated Checkword to include a list of the words that are valid in WWF. Not too useful for adjudication, as WWF does not allow the playing of phonies, however you can use Makewords to search for possible words (after a play, of course, I don’t condone cheating). And knowing the above odd list of additions might be useful in regular WWF play, as normally you might not think to try neologisms like GOOGLE or TEXTED. Also the addition of GI is quite notable as it does not show up on most US 2-letter word lists, as it’s not in TWL or ENABLE (it is in SOWPODS)

Given the popularity of WWF, I’d expect they will continue to refine their word list. It would be nice if they added a TWL option.

UPDATE: WWF 4.02 removed the following words, all to do with Nazis:

DENAZIFICATION, DENAZIFICATIONS, DENAZIFIED, DENAZIFIES, DENAZIFY, DENAZIFYING, HEIL, HEILED, HEILING, HEILS, NAZI, NAZIFICATION, NAZIFICATIONS, NAZIFIED, NAZIFIES, NAZIFY, NAZIFYING, NAZIS

No words were added. I’ll reflect this change when I do the next checkword update, but it’s not significant enough to do a new release.

UPDATE: WWF 4.12 has the following additional words removed. Current as of April 3, 2012:

ABO, ABOS, DARKEY, DARKEYS, DARKIE, DARKIES, DARKY, LEZ, LEZZES, LEZZIE, LEZZIES, LEZZY, WOP, WOPS

Again, no words were added.
