Naming unoriginal Arabic appointees to adverb

Some orientalists has considered neither subject nor predicate accusatives in Arabic as complementary and some Arabic syntax researchers called them special builder and some named them supplementary. But Azarnoosh has named them adverb.
This naming, adverb, because of the correspondence of most of these accusatives with adverb in Persian and English, is correct, exact and also more shortened, illustrative and exclusive than other names. Also finding equivalent and teaching it to others is simpler too.
This syntactic category has two forms: 1. Singular 2. Compound. Most of the singular adverbs can be changed into compound ones while reserving the meaning, usage and grammatical role. Regarding the characteristics of adverb, the definition is as follows: adverb is a meaningful and neither subject nor predicate part of sentence in Arabic syntax which determines the aspect and direction of the sentence in case of being singular or compound and it plays one the eight grammatical roles such as: adverb of time and place, adverb of reason, companionship adverb, intensifier adverb, state adverb, explicating adverb, exception adverb and specialized adverb.
