fix photoA prefix is a syllable put at the beginning of a word to add to its meaning. Prefixes help to form new words. The word “prefix” itself makes use of the prefix “pre”, which means “before”.

“Pre” means “before”

“Fix” means “to fit firmly”.

Therefore “fix” a prefix “before” another word to add to its meaning. On top of that, each prefix has a “fixed” meaning. That is, the meaning the prefix carries is the same every time it is used in front of a “root word”.

Therefore: Prefix + Root Word = New word.

Here are some examples of prefixes:

pre – before

bi – two

de – down, away from

inter – between

dis – not

re – again

trans – across

The italicized words below are made up of the prefix “pre” plus another word. Each italicized word therefore, will carry the meaning of “before” within it.
