Root Explanation

Postfix → It is formed from "post-" (meaning after) and "fix" (from Latin "figere", meaning to fasten or attach). The word "postfix" refers to something that is attached after, particularly in the context of grammar or programming where it is added to the end of a word or expression.

Memory Tip

Think of something being 'attached after' — 'post-' means after, and 'fix' means to fasten.
