Usage

Off of is often used in place of the preposition off in contexts such as she picked it up off of the floor (compared with she picked it up off the floor). Logically parallel to the standard out of, the phrase is recorded from the 16th century (it was used by Shakespeare) and is widely accepted in American English. Nevertheless, it is regarded as incorrect in standard modern British English
