1. Definition + Rich Everyday Explanation

Vary (verb) ( veə ri ) = to make or become different; to change in amount, level, or type; to include a range of different things.

Vary is all about avoiding sameness — like how the weather varies day to day, or how you vary your routine to keep life interesting. It’s the opposite of routine or uniform; things vary when they shift, differ, or offer options. People use it to describe natural changes, deliberate choices, or diversity in groups.

MEANING 1: Change or Differ (Intransitive Verb) — VERY COMMON

As an intransitive verb, vary means things are not the same — they fluctuate or differ naturally. Opinions vary among friends. Prices vary by season. Weather varies wildly. This captures how life isn’t constant — amounts, quality, or types shift over time or between cases.

MEANING 2: Make Different Deliberately (Transitive Verb) — VERY COMMON

As a transitive verb, vary means to intentionally change or diversify something. Chefs vary recipes for excitement. Teachers vary activities to engage students. You vary your workout to build muscle. This is active choice — breaking monotony for better results.
