Does anyone know what this means?
Hey! I am trying to learn Korean and someone sent me a message that says "뭔말인지모르겟여 ㅠ"

Does anyone know what this means?

So far I know that "ㅠ" is like a crying face, and I think the rest of it is saying either I don't understand something or they don't understand something but I am not sure if that is right.

Answer

뭔말인지모르겟여 ㅠ

뭔 = 뭐(what)+는(particle)
말 - words, speech
인지 = 이다(to be)+ㄴ지(GRAMMAR POINT)
모르겟여 is a casual/internet spelling of 모르겠어요 = 모르다(to not know)+겠(GRAMMAR, commonly used with the former as 모르겠다 -> 모르겠어요)

ㄴ지 모르겠어요 - don't know something
인지 모르겠어요 - don't know ... is
뭔말인지모르겠어요 - (I) don't know what (that) word is.

Answer

Well.. It's a texting style writing. You are probably hard to understand this kind of texts.
literally, it means "I don't know what's that means"

"뭔말" -> reduction form of "무슨말". The original form of "모르겟어여" is "모르겠어요" because the pronunciations are same. So the correct form of the sentence is should be "무슨 말인지 모르겠어요"

Answer

Well, It's writen in more spoken words. 
무슨 말인지 모르겠어.ㅠ
