Root Explanation

Labialization → It is formed from "labium" (from Latin, meaning lip) and "-ization" (meaning the process of making or becoming). The word describes the process of modifying a sound to be produced with the lips, hence relating to lips.

Memory Tip

Think of 'lips' ('labium') being involved in a process ('-ization') — that's why labialization refers to the process of producing sounds with the lips.
