más tarde, sí

Question

mas tarde, si

Answer 1

This is such a great question you asked...and not for the translation! This is a really excellent demonstration to you of how those words can change their meaning according to context. They are all right...but they can be all wrong. Only in full context, with the sentences before and after those words can give a full understand of what they mean!

Answer 2

Mas tarde, si

This translates to

but late, if

Now that Quentin has edited the posters original text, this makes my translation look stupid.

Answer 3

Later, yes. Later; Ok.

Answer 4

más tarde, sí.

Is that something like "later, dude" or are you actually answering ""yes, later" or is it a question: "Later, yes?"
