Not having the same characteristics or qualities throughout; varying in form or nature.

Nonuniform → It is formed from "non-" (meaning not) and "uniform" (from Latin "uniformis", meaning having one form). The word "nonuniform" means not having one consistent form or shape.
Think of 'not' ('non-') having 'one form' ('uniform') — that's why nonuniform means lacking consistency in form.
