I have seen both types of sentences:

He jumped off the rock.

He jumped off of the rock.

Are they both grammatical?


Thank you.

  • Can you please use a forward slash (/) when separating options? A backslash isn't used for that purpose in English.

You “jump off“ of (=from) a surface, so ‘jump off of the rock’ and ‘jump off the rock’ are both grammatical, the former is more common in speech but the latter sounds better and less redundant to my ears.

The following guidance is off of Wiktionary

The use of off of as a preposition is now considered tautological or incorrect by some usage guides and is not suitable for formal or business use. Off of can be replaced with on, from or off:

  1. "This is based on (based off of) his first book"
  2. "He took a paper off (off of) his desk".
  3. "I got the information from ("off of") the Internet"

and from Dictionary.com we have this

The phrasal preposition off of is old in English, going back to the 16th century. Although usage guides reject it as redundant, recommending off without of, the phrase is widespread in speech, including that of the educated: Let's watch as the presidential candidates come off of the rostrum and down into the audience.
Off of is rare in edited writing except to give the flavor of speech.

Other examples with off of are

  • Don't take your eyes off of the road.
  • Can I borrow ten dollars off of you?

  • It wan not a joke, I really wanted to know its meaning Commented Mar 31, 2019 at 11:50
  • @KshitijSingh you asked "…meaning of off of, so I guessed you were fooling around. In any case, "off" is the opposite of "on". If I jump off a chair, I am no longer on it. Some people will add an "of" so you can hear I jumped off of a chair The meaning is the same.

    @NikoO No, in this instance "got the information off (of) the Internet" is similar to the meaning of "from". If anything was removed from a text it would be REDACTED or DELETED. I tried looking for a reliable reference for this meaning ("source/from") but couldn't find one. Maybe it's too dialectal to be worth an entry in the dictionary, but it should be listed on the OED, the paid subscription. Unfortunately, I don't have access.
