💡 Grammar Points

Pronouns Stick to Infinitives

When a verb is in its base form (infinitive, like 'conocer'), the little words that stand in for the person or thing receiving the action ('lo', 'la', 'me', 'te') usually attach to the end, forming one word.

Conocer vs. Saber

Use conocer when you know a person, a place, or are familiar with something (knowledge through experience). Use saber when you know a fact, a piece of information, or how to do something (knowledge through intelligence/skill).

❌ Common Pitfalls

Misplacing the Pronoun

Mistake: "Lo quiero conocer."

Correction: Quiero conocerlo. (Both are technically correct, but attaching it to the infinitive is often more natural and simpler in this structure.)

⭐ Usage Tips

Stress Change

When you attach the pronoun 'lo' to the infinitive 'conocer,' the stress shifts to the last syllable of the verb, requiring an accent mark if the original stress wasn't there. (Though 'conocer' already stresses the 'er', for other verbs, this is critical!)

Frequently Asked Questions

Can I separate 'conocer' and 'lo'?

Yes! When you have two verbs (like 'Quiero conocerlo'), you have the option to attach the pronoun ('Quiero conocerlo') or place it before the first conjugated verb ('Lo quiero conocer'). Both are perfectly correct.

How do I make 'conocerlo' feminine?

If you are referring to a woman or a feminine object (like 'la ciudad'), you would change 'lo' to 'la', making the word 'conocerla' ('to know her/it').
