grammaticality - How can I explain to people that the phrase “off of ” is grammatically incorrect?
How can I explain to people that the phrase off of is grammatically incorrect? I‘ve heard this phrase used a lot, especially by Americans (though they aren't the only ones). In my understanding, off of should usually be replaced by off , as in, I took the book off the shelf as opposed to I took the book off of the shelf Am I wrong? Or is there perhaps some simple way I can explain this to most people? Answer I don't know how you can explain to people in general that it's grammatically incorrect, but here is one idea: when you go to a James Brown tribute concert and the singer says "Get up offa that thing" what you could do is to trounce the security guards, climb on to the stage, pounce onto the singer, grab the microphone and say "In fact you should be saying not 'get up offa that thing' but 'get up off that thing' since 'offa' is grammatically incorrect." I'm sure everyone will thank you for your grammatical corrections...
