Answer 2

Here's an example:

I need to find my book: Tengo que encontrar mi libro.

I need to find my daughter: Tengo que encontrar a mi hija.

I need to find a dentist: Tengo que encontrar un dentista.

Mi hija gets the personal a because it's a specific person.

Un dentista does not get the personal a because there's no specific dentist.
