niff without the e. (see: life, wife, fife, strife) The k is arguable (but you can find eloquent people who enunciate it)

I would argue that if we’re going to simplify English we should use one letter for i as in the sound used in knife, and one letter for i as in the sound used in niff, rather than having some other letter in a completely different part of the word (and later in the word no less!) modify the sound. How ridiculous our language is!
