1. Sometimes -ion is added to a bound stem that is closely related to a verb. For instance, in satisfaction -ion is added to the bound stem satisfact. And satisfact is closely related to the verb satisfy: When you are satisfied, you feel satisfaction.

In the table below analyze each of the nouns into a bound stem plus -ion. Then in the Related Verb column write in the verb. To help you with the correct spelling, the related verbs are all listed here so that all you have to do is find each one and write it into its proper blank in the Related Verb column:

admitapprehendcommitdecidedescribedivideexplodeextendintroducepermitreceiverecognizerepeatsatisfysuspect\begin{align*}&\text{admit} && \text{decide} && \text{explode} && \text{permit} && \text{repeat}\\ &\text{apprehend} && \text{describe} && \text{extend} && \text{receive} && \text{satisfy}\\ &\text{commit} && \text{divide} && \text{introduce} && \text{recognize} && \text{suspect}\end{align*}

2. You have seen that the suffix -ion is often added to verbs that end with the suffix -ate, as in educate, education, and legislate, legislation. Because so many nouns end in <ation> people began to use -ation as a single suffix for forming nouns. Often the -ation is added to a verb. Analyze the nouns below into verb plus -ation, showing any changes that occur:

Noun = Verb + Suffix
civilization = +
determination = +
examination = +
information = +
limitation = +
observation = +
recommendation = +

3. Like -ion, -ation is also sometimes added to a bound stem, usually one that is closely related to a verb. Analyze each of the following nouns into a bound stem plus -ation. Then for each noun other than indignation fill in the related verb. Again, the related verbs are listed below:

acclaimapplyexclaimexplainoccupyproclaimreveal\begin{align*}&\text{acclaim} && \text{explain} && \text{reveal}\\ &\text{apply} && \text{occupy}\\ &\text{exclaim} && \text{proclaim}\end{align*}
