Adverbial Modifier

a secondary part of a sentence that describes the circumstantial attributes of an action or state (place, time, purpose, cause, means). The adverbial modifier also defines an action or other attribute in a qualitative or quantitative sense. The adverb is a specialized form of adverbial modifier. Adverbial participles, the oblique cases of nouns, and infinitives may also function as adverbial modifiers. An adverbial modifier may relate to the sentence as a whole (”Now it’s winter there”) or to an individual word in the sentence, to which it is connected either by adjoining or by loose subordination.
