Very means true, real, or actual when used as an adjective, and greatly or exceedingly when used as an adverb. Its precise force depends on whether it identifies something as genuine or intensifies a description.
The word describes an actual son, a particular day, or the true Christ, and it intensifies expressions such as sorry or great. Revised translations sometimes replace it with truly, exceeding, or sore.
The adjective derives from Latin for true. Biblical translation uses several Hebrew and Greek words for its adjectival and adverbial senses.
