To be removed from something or some group of people by some appreciable difference. Modifiers like "a bit" or "apace" are often used between "off" and "from." Tonya stood off from the rest of the party, not speaking to anyone and looking very much ill at ease. Make sure you stand off a bit from the blasting area. I stood off apace from the crowd of bystanders, not wanting to be noticed by the police.
