There are 877 4-letter words containing I in the ENABLE dictionary — 22% of all 3,903 words at this length. I is a one-point tile and the bag holds a lot of them, so these words are less about scoring than about shape: they are what clears a vowel-heavy rack, and in a daily guessing game they are how you test a vowel you have not placed yet.
The I falls in the second position more often than any other, in 508 of them. 24 of them use the letter more than once — hili, ibis, ilia, imid among them, which is the case worth checking twice when a game has told you a letter is present but not how many times.
If you know more than one letter, this page stops being the fast way to find it. Enter what you have in the unscrambler — the Contains, Starts with and Ends with filters combine, and setting both length fields to 4 narrows this list to the handful your letters actually allow.
