Grammar

The word 'Give' is an action word that tells what someone should do. Words that express actions are called verbs. The sentence is imperative (command form), where the verb comes first. Noun (naming word), adverb (modifies verb), adjective (describes noun), and pronoun (replaces noun) don't apply here.

The word 'They' is used in place of a noun (like specific names of people). Words that replace or substitute for nouns are called pronouns. A noun names something, verb shows action, adjective describes, and adverb modifies verbs - none of these fit 'They'.

The word 'late' tells how John 'came' (the verb) - it modifies the verb by describing when or how the action happened. Words that modify verbs are adverbs. Noun names things, adjective describes nouns, pronoun replaces nouns, and verb shows action.
