In English grammar, a nominative absolute is an absolute, the term coming from Latin absolūtum for "loosened from" or "separated",[1] part of a sentence, functioning as a sentence modifier (usually at the beginning or end of the sentence).
It provides an additional information about the main subject and verb.
A noun in the common case or a pronoun in the nominative case is joined with a predicate that does not include a finite verb.
One way to identify a nominative absolute is to add a conjunction and a verb: one can often (though not always) create a subordinate clause out of a nominative absolute by adding a subordinating conjunction (such as because or when) and a form of the verb to be.
