Consider the words 'interloper' and 'pedant'.These are considered as nouns.But when we say John acts like an interloper or He is a pedant,it gives an impression as if both are adjectives as they are qualifying/modifying the noun----John and pronoun----He ,respectively.
Please explain to me why these words are nouns.
Thanks and regards,
Hi kamlesh k
Both of your sentences use "linking verbs". These verbs connect or link the subject to a subject complement. A subject complement describes or identifies the subject. Linking verbs can connect the subject to a noun, a pronoun or an adjective. In your sentences, the subject is linked to a noun and a pronoun respectively.John acts like an interloper or He is a pedant
Hope that helps.
