Please tell me if I have identified the following the sentences correctly as being declarative, exclamatory or impeative:

The Italian word fo "moon" is luna
Declarative

Wow, that's how you say it it Spanish, too
Exclamatory

I have heard the words lunatic and lunacy
Declarative

Lunatic means "insane" and lunacy means "insanity"
Declarative

Well, the word moonstruck means "crazy" or "insane", so it makes sense to me
Declarative

Oh, look at the time
Imperative
