Could of / Should of / Would of
As in, “I could of gone to the store. I should of done my homework. I would of punched you in the face.” Also exhibited in the J. Geils Band song, “Must of Got Lost.” None of that makes any sense whatsoever.
Granted, there are multiple things wrong with the song title but let’s take a look at this: I could (origin) gone to the store. That doesn’t make sense. I could (cause) go to the store. Nope. I could (direction from) go to the store. Again, nope. But, if we use the right word (have), it makes sense: I could have gone, as in “in the past, there was a possibility of going.”
“Of” is not an auxiliary verb. It’s a preposition. A noun follows it. So “could of gone” MAKES NO SENSE.
Perhaps nitpicky, it drives me crazy that people don’t understand the difference between “Could have” and “Could of” (which makes no sense). When we talk fast we say “COULD’VE” not “could of.”
Could have / Should have / Would have
Could’ve / Should’ve / Would’ve
