The Suffix -ize

1. The suffix -ize turns stems into verbs. The suffix -ize is related to -ist in a special way:

Noun or Adjective Noun Verb
capital capitalist capitalize
vocal vocalist vocalize
ideal idealist idealize

Many stems that add -ist to make a noun also add -ize to make a verb.

2. Analyze each of the following words into its shortest free stem plus suffix or suffixes. Show any changes.

Word = Free Stem + Suffix or Suffixes
rationalized = ration + al + iz\begin{align*}\cancel{e}\end{align*} + ed
rationalists = ration + al + ist + s
vaporizer = vapor + iz\begin{align*}\cancel{e}\end{align*} + er
criticizing = critic + iz\begin{align*}\cancel{e}\end{align*} + ing
capitalists = capital + ist + s
capitalize = capital + ize
naturalized = natur\begin{align*}\cancel{e}\end{align*} + al + iz\begin{align*}\cancel{e}\end{align*} + ed
naturalists = natur\begin{align*}\cancel{e}\end{align*} + al + ist + s
itemizing = item + iz\begin{align*}\cancel{e}\end{align*} + ing
realizing = real + iz\begin{align*}\cancel{e}\end{align*} + ing
realist = real + ist
characterizes = character + iz\begin{align*}\cancel{e}\end{align*} + es
civilized = civil + iz\begin{align*}\cancel{e}\end{align*} + ed
victimize = victim + ize
formalized = form + al + iz\begin{align*}\cancel{e}\end{align*} + ed
specialize = special + ize

3. Proofreading Quiz. The nine words in bold type in the following two paragraphs are misspelled. Find the mistakes and write in the correct spelling of each one:

a. The words gyp, gypsy, and Egypt are all related to one another \begin{align*}\overset{historically}{\cancel{\mathrm{historicaly}}}\end{align*}. The word Egypt came first. It is a very old word that goes back to ancient Egyptian times.Then, five hunderd years ago when a lot of dark-\begin{align*}\overset{skinned}{\cancel{\mathrm{skined}}}\end{align*} people moved into Europe Egypt from Asia, many thought them to be from \begin{align*}\overset{Egypt}{\cancel{\mathrm{Egyp}}}\end{align*}, so they were called gypsies. Then because many thought that gypsies often cheated people, their name was shortened to gypped stand for a certain kind of cheat: a gyp. Many people thought that gypsies \begin{align*}\overset{gypped}{\cancel{\mathrm{gyped}}}\end{align*} people.

b. The Greeks believed that there were nine goddesses who were in charge of the arts. These nine \begin{align*}\overset{artistic}{\cancel{\mathrm{artistick}}}\end{align*} \begin{align*}\overset{goddesses}{\cancel{\mathrm{godesses}}}\end{align*} were called muses. If you add the suffix -ic to the word muse, you get music: mus\begin{align*}\cancel{e}\end{align*} + ic = music. Music is the art of the muses. The same base muse is also in the word museum: mus\begin{align*}\cancel{e}\end{align*} + eum = museum. A museum was a place for the muses. So when you attend a \begin{align*}\overset{musical}{\cancel{\mathrm{musicall}}}\end{align*} concert or look at an exhibit in an art museum, you can thank the nine \begin{align*}\overset{Greek}{\cancel{\mathrm{Greke}}}\end{align*} muses.

Teaching Notes.

The suffix -ize is very common and still productive in English. British English often has -ise where American English has -ize, as in civilise vs. civilize..
