# 9.13: Work with Bound Bases

Difficulty Level: At Grade Created by: CK-12

## Work with Bound Bases

1. Elements are the smallest parts of written words that add meaning to the words. There are three kinds of elements: prefixes, bases, and suffixes.

Prefixes are elements that go at the __________ of words and (can/cannot) stand free as words. In the words unpainted and insisting __________ and __________ are prefixes.

Suffixes are elements that go at the __________ of words and (can/cannot) stand free as words. In the words unpainted and insisting __________ and __________ are suffixes.

Bases are elements that carry the core of the word's meaning. In the words unpainted and insisting ___ and __________ are bases. Free bases are bases that __________. Bound bases are bases that __________. Is the base in the word unpainted free or is it bound? __________. Is the base in the word insisting free or is it bound? __________.

2. Each of the following words consists of a prefix and a bound base. You have worked with all of the prefixes in previous lessons. You should find five different bound bases. Analyze each word into its prefix and bound base, showing any assimilation:

Word = Prefix + Bound Base
accept = a$\cancel{d}$ + c + cept
effect = +
commit = +
infect = +
resume = +
submit = +
affect = +
subsume = +
except = +
concept = +
consume = +
include = +
emit = +
conclude = +
assume = +
exclude = +

3. Each of the following words consists of a prefix, a bound base, and a suffix. The bound bases are the same ones you just worked with. Some of the prefixes and suffixes may be new to you. Don't let that bother you. Analyze each word. Show any assimilation and other changes that occur when prefixes and suffixes get added to the bases:

Word = Prefix + Bound Base + Suffix
emitted = + +
intercepting = + +
secluded = + +
transmitter = + +
consumer = + +
perfectly = + +
affection = + +
reception = + +

Word Pyramids. The word hidden in this pyramid contains a bound base that you’ve worked with in this lesson.The base is four letters long. The hidden word also contains an assimilated prefix and a final ‘e’ deletion. In steps two through four, analyze the stems so as to show the assimilation and ‘e’ deletion.
