No. It is an adverb, and modifies verbs and adjectives.
differing can be used as an adjective, e.g. broadly differing circumstances.
a giraffe is broadly.
That is the correct spelling of the adverb "broadly" (widely, or in general terms).
Broadly speaking, everyone should go to the ballots on election day.
The main job of an adverb is to modify a verb. An adverb can also modify and adjective, which is a word that 'tells more about a noun'. So, by modifying an adjective, an adverb is telling you more about the noun. Examples:a really hot dayfreshly laundered sheetsa broadly worded question
it means fast/lively, majestically and broadly
science can be BROADLY classified into chemistry physics n Biology.
Yes. The dictionary says that it is an adverb.
There isn't such a thing as a "plural" or "singular" tense. The tenses are either Present, Past or Future (broadly speaking, there are several subcategories). Singular/plural refer to Number. "Hot" is an adjective, therefore is has neither tense, nor number, only degrees of comparison.
