More About Bound Stems

1. In many words, when you take away the prefix, you have a bound stem left. Knowing that can make it easier to recognize prefixes like dis- and re-.

2. For instance, all of the following words contain either re- or dis-, plus a bound stem that consists of just a bound base and nothing else. Analyze each one into its prefix and bound stem:

Word = Prefix + Bound Stem
require = re + quire
accept = ac + cept
promote = pro + mote
disgust = dis + gust
recess = re + cess
dispute = dis + pute

3. Many words contain a prefix plus a bound stem that includes more than the base. Take the prefix away from each of the following words and see the bound stem that is left over:

Word = Prefix + Bound Stem
deducing = de + ducing
inspector = in + spector
perceptive = per + ceptive
demoted = de + moted
induced = in + duced
prospector = pro + spector
disputing = dis + puting
promotes = pro + motes
requires = re + quires
receptor = re + ceptor

4. True or false:

1. A stem is the part of the word that is left when you take away a prefix or suffix. True.

2. A free stem can stand free as a word. True.

3. A bound stem cannot stand free as a word. True.

4. Some stems contain a base plus one or more prefixes or suffixes. True.

5. Some stems contain only a base. True.

Teaching Notes.

Item 2. The bound base gust means “taste, relish.” There was once the word gust meaning “flavor, enjoyment,” but it is now archaic, so gust can be treated as a bound base. (Notice that we still have the related word gusto)
