In informal British English, we sometimes use have got to instead of have to

例子：

• We have to change the engine oil.
• We’ve got to change the engine oil.

And in even more informal English we sometimes don't even say the have – so it becomes just got to. You might see this in text messages and on social media, for example:

• Got to change the oil.

And there’s one more way to say this: gotta. It’s the most informal of all these forms.

• Gotta change the engine oil.
