Prefixes

Prefixes and suffixes were originally words themselves but they are now groups of letters added to words or to roots to create new words. Prefixes [pre (before) + fix (fasten) = fasten before] are groups of letters placed before words or roots. Prefixes modify or extend the meanings of words and roots.
