1. Look at the word equations on the left. The Greek prefix syn is joined to word parts to make the spelling words. How does the spelling of syn change when it is joined to a combining form that begins with the letter m ? _______________________________________________
with the letter p ? ______________________________________
with the letter b ? ______________________________________
with the letter l ? ______________________________________
2. Look at the four remaining groups of words. Notice that prefixes, as well as suffixes, may be added to Greek combining forms:

anti + onym = antonym

The prefixes a and an mean "not." Write two words formed by adding the prefix a or an to a combining form. __________ __________

Lesson Generalization

Greek prefixes, like Latin prefixes, may be assimilated into another word part. The spelling changes to make more compatible combinations:

in becomes im before m, p, b     in becomes il before l
syn becomes sym before m, p, b     syn becomes syl before l

Greek combining forms can be used in different ways to make English words.

They can be combined with a prefix: synonym
with a suffix: chronic  chronicle
with a prefix and a suffix: synchronize  anonymous
or with another combining form: hypothesis  pseudonym
