Porque se usa "Es que" para preguntas?

Question

I have been talking to some people who start questions with "Es que..." instead of just asking the question with a more relevant verb. > Es que tienes ganas de verlo? instead of > ¿Tienes ganas de verlo? I understand the questions still, but I would love to get some insight of why speakers would use this at the beginning of a question, or in which contexts they are wont to using it.

Answer 1

There is no grammar rule for "es que." It is like the English interjection "well": "Well, do you feel like seeing it?"
