About IOTA
IOTA is the ninth letter of the Greek alphabet, and because it is the smallest letter, it also means a very small amount; its plural is IOTAS. IOTA uses an I, an O and an A with one T. The Greek letters on the list make a good set to learn: ALPHA, BETA, ETA, IOTA, MU, NU, XI, PI, RHO, TAU and more.

IOTA scores 4 points
Before any bonus squares: I 1 + O 1 + T 1 + A 1 = 4. On a double-word square that's 8, on a triple-word 12, and every letter bonus under one of these tiles is applied first.
Example: IOTA as the first play
Later in the game, put the I on a 3L square and IOTA is worth 6 before any word bonus.
