* Preciosa: This is Spanish for "precious" or "beautiful." It's a term of endearment.
* you tengo que ir: This is a mix of English and Spanish. It means "I have to go" or "I need to leave."
* luego hablamos: This is Spanish for "we'll talk later."
* un beso: This is Spanish for "a kiss."
Putting it all together:
The phrase is likely a romantic statement, meaning something like:
* "You're precious, I have to go, but we'll talk later. (Here's) a kiss."
It could also mean:
* "My love, I need to leave, but we'll chat soon. I'll give you a kiss."
The use of "you" in the middle of the Spanish phrase suggests it could be someone who is not completely fluent in Spanish, using a mix of languages to express themselves.
