Summary: The Latin root word *equ* means "equal." This Latin root is the word origin of a good number of English vocabulary words, including ad[*equ*]ate, [*equ*]ator, and [*equ*]ality. The Latin root word *equ* is easily recalled through the word [*equ*]ation, for both sides of an [*equ*]ation are, by definition, "equal" to one another!
