# Clear Adverbial Phrases

A prepositional phrase is a group of words that consists of a preposition, its object and any modifiers that describe the object. You can always tell if a phrase is prepositional by the prepositions *to, of, about, at, before, after, by, behind, during, for, from, in, over, under* and *with*. If a prepositional phrase functions as an adverb, it is called an adverbial phrase and answers the questions *How?, When?* or *Where?*

In technical documentation, always put an adverbial phrase that starts with the preposition *to, before, after, during, from, in* or *under* at the beginning of a sentence, and use a comma to separate the phrase from the independent clause. This will make your instructions easier to understand.
