"Him" is a noun in this sentence. It is what is known as "a trivial use".Is this sentence correct? Why do we use the 'a' with the pronoun?:'What makes you think he is a him'
All words can be nouns when you refer to that word specifically: "Why did you add a "the" when you said "The sympathy was widespread."A better punctuation, which may make the sentence more clear:
What makes you think this person is a "him"?
(a) that has nothing to do with the question asked.If this is specific, shouldn't it be: ''the 'the' ''?
