Unusual Verb?

I came across this word "こうかん" that was defined as "exchange; substitution."  An example sentence was given as:

ちゅうこしゃ を うって しんしゃ と こうかんした。

It looks like こうかん is used as, and conjugated as a verb.  Since I thought all dictionary forms of verbs end in U, how does this one not?  Could it be in a conjugated form already, even though it doesn't look like a conjugation?

Ahh, So!

I didn't think of that.   I figured that the sample sentence would give the use in the sentence the same way they defined it, namely not as a verb.  Arigatou gozaimasu!

<N>(を)する

This is actually a noun + する pair. There are many nouns that can have する added to them to "verbify" them. Well, in truth you're adding をする、then dropping the を because it's understood by context—sometimes the を will be left in for emphasis.

So こうかん(交換) is a noun meaning, as you say, "exchange; substitution", and 交換する or 交換をする means "to exchange; to substitute".
