Anyone who sends obscenity-laced iMessages to their friends already knows that there are certain words that iOS' auto-complete feature just won't help you finish. I've had many a swear remain mistyped or, worse, get corrected to a non-swear despite fairly obvious typos.

Those aren't the only words that iOS won't help you type, though. The Daily Beast has gone through the iOS dictionary and found about 14,000 words that appear to be spelled correctly when typed correctly, but the built-in spellcheck tool won't help you fix them otherwise (at least, not before you type the words enough that the phone adds the terms to your custom dictionary). They found that many of them were simply obscure—words like "sheepshank," "sempstress," and "nephrotoxin" made this list. However, there were plenty of others that are perfectly common but more likely to be objectionable. The following words made their highlight reel.

abortion

abort

rape

bullet

ammo

drunken

drunkard

abduct

arouse

Aryan

murder

virginity

bigot

cuckold

deflower

homoerotic

marijuana

pornography

prostitute

suicide

For the obscure words, the piece speculates that Apple just didn't want to consume space in the stock spellchecking wordlist with words that would be used so rarely. Jillian York, Electronic Frontier Foundation director for international freedom of expression, suggested that Apple's omission of the more frequently used but potentially sensitive words came close to censorship. It "isn't censorship outright," she said, "but it is annoying, and it's denying choice to customers."

In any case, your phone won't prevent you from telling your pals about a drunken prostitute or your homoerotic pornography collection. You'll just have to know how to spell those words on your own.
