Prefixes
All About TOEFL
More TOEFL Exercises
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. Following is
a list of commonly used prefixes and sample vocabulary.
