Adverbs are a type of modifier (the other being adjectives) that modify anything that is not a noun. Like adjectives, by default they come after that which they modify, but word order is flexible.
Morphologically, the productive approach to forming adverbs in MSA is using the ـًا ("-an") case ending. Often these terms are viable in the dialect as learned borrowings. However, the productive way of forming adverbs in the dialect is using the بـ ("bi") prefix; many cases of adverb doublets exist.
Prepositions of location that may be used adverbially without a referent are not repeated here.
These Adverbs affect clauses, conveying the speaker's attitude toward the information being conveyed (e.g. uncertainty, surprise) & the internal integrity of that information (e.g. causality, contradiction); they are used interjectionally & their placement is very flexible.
These Adverbs are exclusively used as auxiliaries to modify verbs.
