– phrases
off and on intermittently.

– origin OE, orig. a var. of of (which combined the senses of ‘of’ and ‘off’).

usage: The use of off of rather than off in phrases such as she picked it up off of the floor is considered to be incorrect in standard modern English. Interestingly, however, off of is recorded from the 16th century, and was used commonly by Shakespeare.
