회화에서 많이 듣게 되는,  "I'll call you up later"는 무슨 뜻일까요? -up-이 들어갔는데 조금이라도 차이가 있지 않을까요? Chat GPT에게 물어봤습니다. 

The phrases "I'll call you later" and "I'll call you up later" essentially convey the same meaning, but there's a slight nuance in tone:

1. "I'll call you later": This is a straightforward and commonly used phrase. It simply means that the speaker will make a phone call to the person at a later time.

2. "I'll call you up later": Adding "up" in this context is more casual or informal. It doesn't significantly alter the meaning, but it might imply a bit more informality or friendliness in the tone. "Call you up" is a more colloquial way of saying "call you." It's often used in casual conversation.

In essence, both expressions suggest that the speaker intends to make a phone call to the person at some point in the future. The difference lies mainly in the level of formality or informality and the tone conveyed.
