Hi, everyone! In one of the texts I'm currently reading I stumbled upon such part : "You got to come out sometime,” he said. “I'll wait here till you do." What does this "got" mean in the first sentence? I mean, in this particular context.
I will appreciate your help!

Question

Answer

They are all roughly equivalent, especially in more informal language. 'Got' tends to be less formal and more casual.

'I got to' = 'I have to' = 'I need to'

There can be vary degrees to how 'obligatory' the thing is in regular speech; it's not incredibly precise. 'I must' is the highest level obligation, but this is mostly found in written form.

Answer

It's expressing obligation.

you got to [+ base verb] = you have got to [+ base verb] = you have to [+base verb}

You can also hear other varieties in casual speech like "you gotta" or "ya gotta."
