Here's a breakdown:
* Oye: This is a casual way of saying "Hey" or "Listen".
* Cómo: This means "how".
* Va: This is the third-person singular present tense of the verb "ir" (to go), and in this context, it implies "how are things going" or "how are you doing".
So, "Oye cómo va" is a friendly and informal way to ask someone how they are doing.
