Step-by-step explanation:
i'm literally 17 and just realized I don't know anything about grammar but bare with me.
adjectives: describes a noun (person, place, or thing)
adverbs: i HAVE NO CLUE. Adverbs describe an action(verb)
articles: tend to be very small words (a,an,the,and)
subject: who is the star of the sentence? who are we giving the attention?
linking verb: links the subject with an action
example: Grandpa(subject) IS(link) sleeping(action)
predicate noun: How we redefine the subject later in the sentence as a different thing (noun)
example:
My sister(subject) is an absolute lunatic(predicate noun, I called my sister by a different "thing").
