1. Prefixes (come at the beginning of words)
 Tend to give words direction & emotional charge.
2. Bases (come in the middle of words)
 Give words their basic meaning.
3. Suffixes (come at the end of words)
 Determine the part of speech or tense of a word.

6. Functions of prefixes A prefix can NEGATE a base
 un + able = unable (not able)
 non + sense = nonsense (doesn’t‘ make sense)
A prefix can give a base DIRECTIONAL force
 sub + marine = submarine (under the ocean)
 ex + port = export (carry out)
A prefix can INTENSIFY or WEAKEN a base’s meaning.
 super + human = superhuman (more than human)
 sub + standard = substandard (less than standard)

7. in + probable  improbable*
Assimilation
Sometimes the spelling of a prefix changes when it meets a base that begins with a consonant (b,c,d,f,g).
In this case, the final consonant of the prefix “turns into” (ASSIMILATES) the first consonant of the base.*
The result is a double consonant near the beginning of the word.
ob + pose  oppose
ad + rive  arrive
in + probable  improbable*
