Word Choice – Off or Off of

Andy’s question: “Is it proper grammar to use ‘Billy jumped off of the ladder’? I don’t think so. I think it should be ‘Billy jumped off the ladder.’”

BizWritingTip response: “Off” and “of” are both prepositions. A preposition is a word mainly used before a noun or pronoun to show its relationship with other words. Some examples of prepositions are with, by, to, in, to, into, between, on, off and of.

If you keep the placement rule in mind, it makes no sense to have a preposition (off) before another preposition (of). Therefore, grammar books agree off of is superfluous and should be avoided when writing.

Examples (correct when writing)

Billy jumped off the ladder.
The box fell off the shelf.

Interestingly, off of can be found in the works of early English writers going back to the 16th century, e.g., Shakespeare’s play Henry VI. But times change.

In speaking, off of is considered an Americanism. The Brits and Canadians more commonly use off by itself.

Note: Nowadays, a preposition can also be the last word in a sentence whether you are writing or speaking.
