Root Explanation

Proportional → It is formed from "pro-" (meaning for or in favor of) and "portio" (from Latin, meaning part or share) and the suffix "-al" (meaning relating to). The word "proportional" refers to something that is in relation to or corresponds to a part or share of something else.

Memory Tip

Think of something that is 'for' ('pro-') a certain 'part' ('portio') — that's why proportional means relating to a part of something.
