Showing respect and submission to someone else's opinions or wishes.

Deferential → It is formed from "defer" (from Latin "deferre", meaning to carry down or yield) and the suffix "-ential" (meaning relating to or characterized by). The word "deferential" describes a quality of yielding or showing respect to someone, particularly in a hierarchical context.
Think of 'yielding' ('defer') to someone in authority, and the '-ential' part means relating to that quality of respect.
