What does quien necesitas mean?

"Quien necesitas" is grammatically incorrect in Spanish. It's missing a word to make sense.

However, it's likely you meant to ask:

"¿Quién necesitas?"

This translates to "Who do you need?"

Here are some other ways you could phrase this question in Spanish:

* "¿A quién necesitas?" - "Who do you need?" (More formal)

* "¿Quién te hace falta?" - "Who are you missing?"

* "¿A quién estás buscando?" - "Who are you looking for?"

It's important to consider the context of your question when choosing the best Spanish phrase.
