Root Explanation
Inexpressible → It is formed from "in-" (meaning not) and "expressus" (from Latin, meaning to press out or to express) and the suffix "-ible" (meaning capable of). The word "inexpressible" means not capable of being expressed or described.
Memory Tip
Think of something that cannot be 'pressed out' or 'expressed' — 'in-' means not, and 'expressus' means to express.
