Root Explanation

Nonlinearity → It is formed from "non-" (meaning not) and "linear" (from Latin "linearis", meaning relating to a line) and the suffix "-ity" (meaning the state or condition of). The word "nonlinearity" refers to the state or condition of not being linear, indicating a relationship that does not follow a straight line or proportionality.

Memory Tip

Think of 'not' ('non-') being applied to something 'relating to a line' ('linear'), which helps you remember that 'nonlinearity' describes a situation that does not follow a straight path.
