Have you ever heard of parallax in astronomy?

Yeah, it's that effect that helps us measure distances to stars, right?

Root Explanation

Parallax → It is formed from "para-" (meaning beside or alongside) and "allaxis" (meaning a change or alteration). The word describes the apparent change in position of an object when viewed from different angles, hence the idea of something being beside or alongside in perspective.

Memory Tip

Think of viewing something from 'beside' ('para-') and noticing a 'change' ('allaxis') in its position — that’s what parallax means.
