1. (diminutive) Very small.

   ‎micro- + ‎organism → ‎microorganism

3. (metric units) One millionth.

Usage notes

• (one millionth): Officially, micro- is abbreviated as µ- (the Greek letter mu); for example, one second is 1s, so one microsecond is 1µs. However, for many purposes this is inconvenient, so writers often use either u- (for its similar appearance to µ-) or mc-, producing, for example, 1um (one micrometer) and 1mcg (one microgram).

Synonyms

• (diminutive): mini-, nano-, -ette, -ee, -y, -icle/-cule/-ule/-ole

Antonyms

• (antonym(s) of “diminutive”): super-, supra-, hyper-, ultra-, uber-, macro-, arch-, over-, mega-, giga-, -zilla, grand, great
