Conversation

I just learned about the concept of a homologue in biology class.

Oh really? What does that mean exactly?

It's basically something that has a similar structure or function, like a related organ or part.

That's interesting! I didn't know there were specific terms for that.

Root Explanation

Homologue → It is formed from "homo-" (from Greek "homos", meaning same) and "-logue" (from Greek "logos", meaning word or reason). The word "homologue" refers to something that has the same relation or structure as another, hence the idea of similarity or sameness.

Memory Tip

Think of 'same' ('homo-') and 'reason' or 'word' ('-logue') to remember that a homologue refers to something that is similar or has the same structure as something else.
