Should have, not should of

7:57

It's I

7:57

should have studied harder, not I should

8:00

of studied harder.

8:02

Now, I think people use of because when

8:05

have is contracted after a consonant

8:07

sound, it sounds the same as the weak

8:11

form of of. Have contracted, of of

8:15

contracted, of. Should have, should of.

8:20

Would have, would of.

8:22

Could have, could of.

8:24

That of sound tricks our brain into

8:27

thinking it's of, and people make the

8:29

mistake of saying it or writing it. In

8:32

fast speech, we often use the informal

8:34

contractions shoulda, woulda, and

8:36

coulda, which don't sound like they

8:39

contain have, either.

8:41

So, the structure to form a clause with

8:43

a past modal is modal verb plus have

8:46

plus past participle.

8:49

I should have called her.

8:51

But, in speech, we tend to use

8:53

contractions. I should have called her.

8:55

This makes your English sound more

8:57

natural than if you use the full form.

9:00

They would have bought it if it had been

9:02

cheaper. You could have been hurt. We

9:05

also use the same structure with other

9:07

modal verbs like must and might. I hear

9:11

must of and might of, but again, they're

9:14

not correct. She must of already gone

9:17

home.
