A word that ends in the suffix -ion but is not a noun?

This is a bit of a trick question! The suffix "-ion" is almost always associated with nouns.

While there might be some obscure or technical exceptions, it's very rare to find a word ending in "-ion" that isn't a noun.

Let's think about why:

* Etymology: The "-ion" suffix often comes from Latin and Greek words, and in those languages, it typically signifies a noun.

* Grammar: English grammar usually uses "-ion" to form nouns, particularly abstract nouns like "action," "decision," or "creation."

Possible "exceptions" are rare and usually involve:

* Verbs in specific contexts: You might see "-ion" used in a verb form like "to caution" or "to question," but these are still closely related to the noun form.

* Technical terms: In specialized fields, there might be uncommon words with "-ion" that aren't strictly nouns.
