How do you say would / should / could have, but...For example, I would have came to see you yesterday, but I had to work instead.

Would have - ta pral, or sometimes te pral
Should have- te dwe
could have - te ka, te kab, te kapab

I would have come to see you but I had to work instead.
M ta pral vini wè w, men mwen te oblije al travay.

You should have eaten the sandwich.

You could have warned me about it.
Ou te ka avèti mwen de sa.
