Strategy for this list

I is worth 1 in Scrabble and is the second-most-common vowel in English. I starts fewer words than A or E (~3,500) but includes essential short plays (IF, IN, IS, IT) and the entire -ING family. High-value I-openers include IZAR, IAMBIC, IVORY. In Wordle, I is common in position 2 and 3 but rarely in position 1 for answers — an I-opening guess is usually testing for I in interior positions, not the front.
