excitement = + + ment
explorer = + +
excluding = + +
exclaiming = + +
exposure = + + ure

3. Ex- means “out, out of, from.” In the right-hand column below you are given the meaning of the bound base in each word. Analyze each word into its three elements and be ready to discuss how the meanings of the prefix and the bound base lead to the meaning of the word:

Word = Prefix + Bound Base + Suffix Meaning of Base
excepted = + + “take, seize”
excesses = + + “go, withdraw”
exceeding = + + “go, withdraw”
exhibits = + + “hold, possess, have, handle”

4. All of the words in each of the following four sets contain the same bound base. Each word also contains a prefix and a suffix. Analyze each word in each set into prefix plus bound base plus suffix. Show any assimilation.
