Nouns are always modified by an adjective or adjective like word; but other words can be modified grammatically, even whole sentences 

The drunken young man slipped awkwardly into a ditch although he seemed unhurt.

How (i.e. in what manner...) did the man slip?

He slipped... awkwardly into a ditch.

A word that adds extra information or detail to the action told by the verb is called an adverb and, not surprisingly, if it is a phrase, it is called an adverbial phrase.

Notice that the sentence above contains two adverbials - the adverb, awkwardly which tells about the manner of the action and the prepositional phrase, into a ditch which tells about the place of the action.
