Intensive verbs are commonly known as linking verbs, or copular verbs. The have the following structure: Subject+Linking Verb+Subject Complement. The Subject Complement can be a noun, (i.e., a predicate nominal), an adjective (i.e., a predicate adjective) or an adverb (i.e., adverbs of time or place, and prepositional phrases.
She is my doctor.
He is my teacher.
She is nice.
Those people are married.
He seems young.
You look good.
Sam is in the car.
The party is tomorrow.
If the subject complement (SC) modifies other nouns, then it's an adjective:
She is nice => She is a nice person.
He seems young => He is a young man.
Those people are married => Those are married people.
If the SC answers the question Where? or When?, then it's an adverb:
Sam is in the car => Where is Sam?
The party is tomorrow => When is the party?
A SC that doesn't fit the above distributional patterns is a noun.
She is my doctor => She = a doctor
He is my teacher => He = a teacher
They are cats => They = cats
Note, there's no reason to memorize the entire list of linking verbs. There's a simple test you can use: replace the verb with e.g., is, am, was, were, been, etc.
I love baseball.
*I am baseball. ('love' is not a linking verb in this sentence)
I became a priest.
I am a priest. ('became' is a linking verb in this sentence)
She looks at me all the time.
*She is at me all the time. ('looks' is not a linking verb in this sentence)
She looks good.
She is good. ('good' is a linking verb in this sentence)
