FAQs

How do I use "that should have" in a sentence?

Use "that should have" to indicate something that was expected or necessary to happen in the past but did not. For example, "The package should have arrived yesterday" suggests the package was expected but didn't arrive.

What are some alternatives to "that should have"?

You can use alternatives like "that was supposed to happen", "that ought to have", or "that was meant to be" depending on the context.

Is "that should of" grammatically correct instead of "that should have"?

No, "that should of" is grammatically incorrect. The correct form is "that should have". "Of" is a preposition, while "have" is an auxiliary verb used to form the perfect tenses.

"That should have" implies an obligation or expectation that was not met. "That could have", on the other hand, suggests a possibility that existed but did not materialize.
