Other parts of speech as adverbs

Many words of other parts of speech may also occur as adverbs. For example, several Persian adverbs are identical to the adjectives of corresponding meaning:

nevisande ye xub good writer U xub minevisad. He writes well.
sedâ ye âheste soft voice Man âheste goftam. I said softly.

Some adjectives have already been derived from a noun by the suffix “-âne” is. A few still need the suffix “”-âne” to become an adverb:

jang e javânmardâne fair fight U javanmardâne jangid. He fought fairly.
badbaxt unfortunate badbaxtâne unfortunately

Also, some nouns occur as adverbs:

ŝab night Man ŝab miresam. I will arrive at night.

Pure adverbs

But there are also pure adverbs. They do not occur as a different part of speech:

sepas then hargez never
ŝâyad maybe aknun now

Some Arabic loan words ending with “-an” and possibly their counterparts, which are formed by the assistance of a prefix and the associated noun, belong to the pure adverbs, as well:

Noun Meaning Adjective Meaning Adverb Meaning
sor’at quickness sari’ quick sari’an; besor’at quickly
ŝeddat strength ŝadid strong ŝadidan; beŝeddat strongly

Comparative and comparison

Adverbs whose meaning permits it can be treated like adjectives in terms of the comparative and comparison:

Man behtar minevisam. I write better.
Ânhâ zudtar âmadand. They came earlier.
Injâ az hamejâ arzântar miforuŝand. Here are sold cheaper than anywhere else.

The counterpart to the English “as … as” and “the … the …” is formed by harce (whatever). In both cases the comparative is used:

Harce zudtar u râ biâvarid. Bring him as early as possible.
Harce biŝtar, behtar. The more the better.
Harce kamtar bexori, lâqartar miŝavi. The less you eat, the slimmer you will. 

Interrogative adverbs

You can ask for time, place, and manner by interrogative adverbs:

Key gofti? When did you say?
Cegune miravi? How do you go?
Kojâ budi? Where were you?
Candvaqt mimâni? How long are you staying?
Ceqadr miŝavad? How much is that?

Order of adverbs

If there are adverbs of various types in a sentence, then their order is as follows: time – manner – place:

Diruz tanhâ ânjâ budam. Yesterday I was there alone.
