The Suffix -ion

1. The suffix -ion is used to turn verbs into nouns. Analyze each of the following nouns into verb plus -ion:

subtraction = +
collection = +
communication = +
perfection = +
infection = +
invention = +
possession = +
supervision = +
appreciation = +

2. Try some the other way around. Add -ion to each of the following verbs to turn them into nouns:

Verb + Suffix = Noun
educat\begin{align*}\cancel{e}\end{align*} + ion = education
instruct + =
legislate + =
contribute + =
accommodate + =
constitute + =
express + =
demonstrate + =
restrict + =
distribute + =
decorate + =
indicate + =

3. You've seen that -ion is very often added to free stems - namely, verbs - to turn them into nouns. It is also often added to bound stems - again to turn them into nouns. Analyze each of the following nouns into bound stem and -ion
