Adverbs

Adverbs describe verbs, adjectives, or other adverbs. Some are formed from adjectives; others are irregular or fixed.

Irregular: different word from the adjective

The adjective and adverb are not the same word — learn pairs.

• good → well (She sings well.) — «yaxşı oxuyur»
• fast → fast (same form) — eyni yazılış
• hard → hard (work hard) vs hardly (= almost not) — hardly = demək olar ki, heç

Regular: add -ly

Many adverbs of manner use adjective + -ly: quick → quickly, careful → carefully.

• Spelling: happy → happily (y → i), terrible → terribly.
• After linking verbs describing how someone does an action, use the adverb: She spoke clearly.

When we do not add -ly

• With certain verbs — fixed adverbial forms: go home, sleep well, sit still, arrive early/late (not *homely* in this sense).
• Flat adverbs — same as adjective in informal English: drive slow / slowly, real / really (formal writing prefers slowly, really).
• Some words are adverbs as they are — not formed from -ly: often, seldom, never, here, there, today, still, even.
