A word using the suffix -ation?

Question

I'm not asking for all of my homework done, just help on one question, so don't accuse me of cheating.

-ation is "the act of". I can only think of nouns that end in -nation, though. Any ideas?

Answer 1

Abdication

Affirmation

Anticipation

Assasination

Celebration....

Answer 2

fixation divination defenestration illumination desiccation frustration

ation makes a verb into a noun. fixation is the act of being fixated, etc.
