Why won't my iPhone learn curse words? Can I force it to?
Back in the early days of the first generation iPhone, the iPhone was a liberal, open-minded hippie device that would learn any word you threw at it. The iPhone dictionary, like it does for most words now, would adapt to even the filthiest word you could muster after you had turned down its suggested correction 3 times. However, somewhere along the line -- Rupert Murdoch, the Waltons (of Wal-Mart, not TV), or maybe the people who own Blockbuster Video -- got a hold of the iPhone dictionary and blacklisted words they considered offensive.
That's right. My fucking iPhone won't learn curse words. Won't learn fuck. Won't learn shit. Etc.
Good news is, you can make it learn. You're the boss. Bad new is, the workaround is stupid and annoying, but at least it is simple.
Want your iPhone to let you say "fucking" instead of "ducking"? Add the word "fucking" as a contact. Same goes for all your other filthy mouth words.
