Root Explanation

Denominator → It is formed from "de-" (meaning down or away) and "nominare" (meaning to name). The word refers to the part of a fraction that names the whole, indicating how many equal parts the whole is divided into.

Memory Tip

Think of 'naming' ('nominare') the total parts of something 'down' ('de-') — that's why a denominator tells you how many parts make up a whole.
