Question

1. Middle school is the same.
2. Elementary school is the same.
3. Middle school is not the same as elementary school.
4. Middle school is different from elementary school.
------------------
In each sentence, Is 'same' an adjective or a pronoun?

#3 is the same as #4 in meaning.
If 'same' is the opposite of 'different,' is 'same' an adjective? Or is 'same' a pronoun?

Answer 1

It's an appositive. "She is my teacher." "She is not my teacher." 'teacher" is the appositive, in this case a noun. "same" is an adjective in these sentences. "...is the same...", used as an appositive, as in "The tree was tall."
