Usually (but not always, as we shall see), an absolute phrase (also called a nominative absolute) is a group of words consisting of a noun or pronoun and a participle as well as any related modifiers . Absolute phrases do not directly connect to or modify any specific word in the rest of the sentence; instead, they modify the entire sentence, adding information. They are always treated as parenthetical elements and are set off from the rest of the sentence with a comma or a pair of commas (sometimes by a dash or pair of dashes). Notice that absolute phrases contain a subject (which is often modified by a participle), but not a true finite verb .
