I was reading about some homological theories in math class today.

Oh really? That sounds complicated but interesting!

Root Explanation

Homological → It is formed from "homo-" (from Greek "homos", meaning same) and "logia" (from Greek "logia", meaning study or discourse). The word "homological" refers to the study or discourse of things that are the same or similar in some way.

Memory Tip

Think of 'same' ('homo-') and 'study' ('logia') to remember that 'homological' relates to the study of similarities.
