Ever and never are adverbs. Adverbs are words that describe a verb, an adjective or another adverb.
For example, when we say he laughs loudly, the adverb loudly describes the way he laughs.
We usually use ever and never with the Present Perfect, but ever and never can be used with other tenses too.
Ever means 'at any time' and never means 'not at any time'
We use ever with questions when we use it with the Present Perfect Tense.
We use never with negative sentences when we use it with the Present Perfect.
We often use ever with superlative adjectives with the Present Perfect Tense .
We do not use never and not together in the same sentence because both of them has a negative meaning.
