Root Explanation

Nonlinear → It is formed from "non-" (meaning not) and "linear" (from Latin "linearis", meaning relating to a line). The word "nonlinear" describes something that does not follow a straight line or a direct path.

Memory Tip

Think of 'not' ('non-') being applied to something 'related to a line' ('linear') — that's why nonlinear means not following a straight line.
