Understanding of Adverbial Clause

Adverbial clause is a word that functions as an adverb. In other words it contains subjects (explicit or implied) and predicates, and modifies verbs.

General form (formula):

Subject + predicate + conjungtion + subject + predicate.


Explicit Subject I: I saw Joe when I went to the store.
The subject is implied: he quietly inorder to appear polite.

As for some opinions about the adverbial clause, one of them according to Sidney Greenbaum and Randolph Quirk, the adverbial clause serves as a meaningful addition or disjunctions. In their functions they are like adverbial phrases, but because of their function for greater assertiveness, they are more often like proportional phrases. (Greenbaun and Quirk, 1990): here is an example of an adverbial clause comparison with proportional adverb:

We left after the speeches ended. (adverbial clause)
We left after the end of the speeches (adverbial prepoprepositional phrase)

If using if, then the sentence is: I can’t clean the house if you don’t go. (I can’t clean the house if you don’t leave).
