Conversation

Have you ever heard of a colloid in science class?

Yeah, I think it's something like a mixture, right?

Exactly! It's where tiny particles are suspended in a liquid.

Root Explanation

Colloid is formed from "kolla" (meaning glue) and "eidos" (meaning form or shape) in Greek. The term describes a substance that has a glue-like consistency, where particles are dispersed throughout a medium without settling.

Memory Tip

Think of 'glue' ('kolla') that holds things together in a specific 'form' ('eidos') — that's why colloids have a glue-like consistency.
