If so, here the answer:
It is usually used as a polite response when someone thanks you for doing something. It’s a way to acknowledge their gratitude.
I still hear it a lot. Together with so many alternatives, like “no problem”, " happy to help", “don’t mention it”, " glad to assist", “anytime”, “it was nothing”, “my pleasure”, " sure thing"… and I’m sure there are more.
I think OP was asking what it means as in how it came to haventhe meaning you describe. “You are welcome” seems to be a completely arbitrary thing to say and out of context.
Other commenters here explained it’s supposed to mean “you are welcome to my assistance” basically - which makes sense, but in the short form it makes little sense if you arenot familiar with the origins of the phrase (as I was until now)
Are you seriously asking?
