The adverb: formation, suffixes and meaning kinds

By meaning adverbs fall into five kinds. Adverbs of manner show how an action is done: jim (silently), yayov (on foot), birma-bir (one by one). Adverbs of time show when and answer qachon?: endi (now), hozir (at the moment), doimo (always). Adverbs of place show where and answer qayer(ga, da, dan)?: ichkarida (inside), tashqarida (outside), olg‘a (forward). Adverbs of quantity-degree answer qancha?: sal (a bit), ancha (rather), ko‘p (much). Adverbs of purpose-cause show the reason or aim of an action: ataylab (on purpose), atayin, noiloj (of necessity). Purpose-cause adverbs are far fewer than the others.
