What is a prefix?

Answer 1

A prefix is a word part added to the beginning of a word to create a new word with a different meaning.

Examples : refill , undo, incomplete, precooked

(Letters added to the end of a root or word are a suffix.)

In science a prefix is used to modify the size of a base unit by giving a multiplier, for example:

The base unit is a gram; "units" of different sizes are:

kilogram - each is 1000 grams

milligram - each is 1/1000 grams.
