Here's a breakdown of the phrase:
* No: This is the Spanish word for "no."
* te: This is the object pronoun meaning "you."
* entiendo: This is the verb "to understand" in the first person singular present tense.
* pa: This is a slang abbreviation of "para," which means "for" or "to."
* nada: This means "nothing."
So, the phrase literally translates to "I don't understand you for nothing."
In English, it's more natural to say:
* I don't understand you at all.
* I have no idea what you're saying.
* I'm completely lost.
The phrase is used to express confusion or frustration when someone doesn't understand what another person is saying.
