Home / Grammar exercises / Level B1 / Preposición «a» con complemento directo
A summary table with the cases where the direct object takes the preposition a (named people and animals, specific people) and the cases where it does not (unspecified people, things, places, the verb tener). Then you match examples with the rules and practise.
When it is a specific person or a named animal: He visto a Luis, Quiero mucho a mi gato.
Because it is not a specific person, just any waiter. With a specific one you use it: Buscan al camarero que les atendió.
No: places go without a in standard Spanish: Conozco Toledo, Visité Sevilla. Tener meaning possession does not take a either: Tiene tres hijos.
