Direct object pronouns in Spanish are words like "lo," "la," "los," and "las."

These words help us replace the nouns that are getting the action in a sentence.

Here are some important rules to remember:

1. Position:

   • You put the pronoun before the verb that shows the action. For example:
     Lo veo means "I see him."

   • If you’re using an infinitive verb (a verb that hasn't been changed), you attach the pronoun to the end. For example:
     Voy a verlo means "I’m going to see him."

2. Examples:

   • When using a conjugated verb (a verb that has changed for the subject), you might say:
     Ella la compra, which means "She buys it."

   • When using an infinitive, you could say:
     Quiero conocerla, meaning "I want to meet her."

3. Compound tenses:

   • In past perfect tense, which talks about something that happened before another event, you could say:
     Lo había visto, which means "I had seen him."

Knowing where to place these pronouns can really help you get better at speaking and writing in Spanish.
