Words that contain the letter I come up constantly in tile games, crosswords and daily letter puzzles, and this page gathers all 2,783 of the fifteen-letter ones. The most useful are the common words at the top of the list; the rare ones at the bottom are worth knowing when you need to hook onto an awkward board position. BENZODIAZEPINES is the top scorer here, worth 38 points before any board multiplier.
How to use this page
Use this list in two ways. Browse it to learn the words that contain the letter I, common ones first, or search it by typing your own letters, with question marks for blanks, to see only the words you can make. Every word shows its classic tile score, and linked words open a page with all their sub-words.
Tips
Hooks are single letters added to the front or back of an existing word to make a new one, and they are the cheapest way to score in a crowded game. Look through the words on this page for ones that become a different valid word with one more letter, or that can be formed by extending a shorter word already on the board. Suffixes such as S, ED, ER and ING, and prefixes such as RE and UN, do most of the work. A hook lets you play a second word in parallel and collect both scores.
Questions

Why are some of these words unfamiliar?
