Question

The sky was cloudy.We postponed our journey (use nominative absolute)

Answer 1

The answer is The sky being cloudy, we postponed our journey.

A nominative absolute is a noun phrase that begins or ends a sentence. The phrase has no grammatical connection with the rest of the sentence. Most nominative absolutes contain a participle or participial phrase which modifies the noun or pronoun.

Answer 2

As the sky was cloudy, we postponed our journey.

Nominative absolute is used for describing the main subject and the verb, as per the rules of English Grammar.

Usually, a conjunction and another verb are added to a sentence, to mark the absolute part of that sentence.

Also, some subordinating conjunctions may be included for indicating the nominative absolute, which can be turned into subordinate clauses in the sentences.
