8.14: Review of Prefixes, Stems, and Suffixes

Difficulty Level: At Grade Created by: CK-12

Review of Prefixes, Stems, and Suffixes

1. Analyze each of the following words into their prefixes, stems and suffixes as indicated in the formulas given in the middle column. ‘Pr’ equals ‘Prefix’, ‘St’ equals ‘Stem’, and ‘Su’ equals ‘Suffix’. Remember that some stems consist of just a base. Be sure to show all cases of final <e> deletion, twinning, changing of <y> to <i>\begin{align*}<\mathrm{i}>\end{align*} and assimilation:

Word Formula = Analysis

2. Combine the following prefixes, stems, and suffixes. Again, be sure to show all changes that occur when the elements combine:

Prefixes, Stems, and Suffixes = Word
un + ad\begin{align*}\cancel{d}\end{align*} + p + prov\begin{align*}\cancel{e}\end{align*} + ed = unapproved
dis + a\begin{align*}\cancel{d}\end{align*} + p + point + ment + s = disappointments
in + form + er + s = informers
a\begin{align*}\cancel{d}\end{align*} + c + cid + ent + al + ly = accidentally
re + o\begin{align*}\cancel{b}\end{align*} + cur + r + ing = reoccurring
o\begin{align*}\cancel{b}\end{align*} + p + portun\begin{align*}\cancel{e}\end{align*} + ist + s = opportunists
su\begin{align*}\cancel{b}\end{align*} + g + gest + ion + s = suggestions
sub + tract + ion = subtraction
o\begin{align*}\cancel{b}\end{align*} + p + posit\begin{align*}\cancel{e}\end{align*} + ion = opposition
in + de + pend + ent + ly = independently
i\begin{align*}\cancel{n}\end{align*} + l + lustr + at\begin{align*}\cancel{e}\end{align*} + ion + s = illustrations
a\begin{align*}\cancel{d}\end{align*} + s + sort + ment = assortment
a\begin{align*}\cancel{d}\end{align*} + s + sign + ment = assignment
i\begin{align*}\cancel{n}\end{align*} + l + lus + ion + s = illusions
in + vent + or + s = inventors
