## 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 \begin{align*}<\text{i}>\end{align*}, and assimilation:

Word Formula = Analysis
misaddressed Pr\begin{align*}^1\end{align*} + Pr\begin{align*}^2\end{align*} + St + Su = mis + ad + dress + ed
assuring Pr + St + Su =
misinforms Pr\begin{align*}^1\end{align*} + Pr\begin{align*}^2\end{align*} + St + Su =
submariner Pr + St + Su =
successfully Pr + St + Su\begin{align*}^1\end{align*} + Su\begin{align*}^2\end{align*} =
observers Pr + St + Su\begin{align*}^1\end{align*} + Su\begin{align*}^2\end{align*} =
illustrating Pr + St =
unimpressed Pr\begin{align*}^1\end{align*} + Pr\begin{align*}^2\end{align*} + St + Su =
reoccurring Pr\begin{align*}^1\end{align*} + Pr\begin{align*}^2\end{align*} + St + Su =
adventurers Pr + St + Su\begin{align*}^1\end{align*} + Su\begin{align*}^2\end{align*} =
disappearing Pr\begin{align*}^1\end{align*} + Pr\begin{align*}^2\end{align*} + St + Su =
inquirers Pr + St + Su\begin{align*}^1\end{align*} + Su\begin{align*}^2\end{align*} =
suppliers Pr + St + Su\begin{align*}^1\end{align*} + Su\begin{align*}^2\end{align*} =
unaccompanied Pr\begin{align*}^1\end{align*} + Pr\begin{align*}^2\end{align*} + St + Su =
uninvolved Pr\begin{align*}^1\end{align*} + Pr\begin{align*}^2\end{align*} + St + Su =
misassigned Pr\begin{align*}^1\end{align*} + Pr\begin{align*}^2\end{align*} + St + Su =
subscribers Pr + St + Su\begin{align*}^1\end{align*} + Su\begin{align*}^2\end{align*} =
disadvantaged Pr\begin{align*}^1\end{align*} + Pr\begin{align*}^2\end{align*} + St + Su =
unassisted Pr\begin{align*}^1\end{align*} + Pr\begin{align*}^2\end{align*} + St + Su =
sufferers Pr + St + Su\begin{align*}^1\end{align*} + Su\begin{align*}^2\end{align*} =
unaffected Pr\begin{align*}^1\end{align*} + Pr\begin{align*}^2\end{align*} + St + Su =
substituting Pr + St + Su =
straightened St + Su\begin{align*}^1\end{align*} + Su\begin{align*}^2\end{align*} =
occupies Pr + St + Su =

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 + prove + ed = un + a\begin{align*}\cancel{d}\end{align*} + p + prov\begin{align*}\cancel{e}\end{align*} + ed
dis + ad + point + ment + s
in + form + er + s =
ad + just + er + s =
ad + cid + ent + al + ly =
re + ob + cur + ing =
ob + portune + ist + s =
sub + gest + ion + s =
sub + tract + ion =
ob + posite + ion =
in + de + pend + ent + ly =
in + lustr + ate + ion + s =
ad + sign + ment =
in + lus + ion + s =
in + vent + or + s =
ad + opt + ion =
