💡 Grammar Points
The attached 'lo'
The 'lo' at the end means 'it' or 'him.' It only sticks to the end when the verb is in its base form (like 'perder') or a command. Otherwise, it jumps to the front of the verb.
Stem-changing verb
Notice how the 'e' in 'perder' changes to 'ie' in most forms (like 'lo pierdo'), but stays as 'e' when you say 'we' or 'you all'.
❌ Common Pitfalls
Pronoun Placement
Mistake: "Yo quiero lo perder."
Correction: Yo quiero perderlo.
⭐ Usage Tips
It vs. Him
Remember that 'perderlo' can mean 'lose it' for a masculine object (like a 'teléfono') or 'lose him' for a person. Context is key!

💡 Grammar Points

While 'perder' usually means 'to lose,' when you talk about a bus or a flight, it naturally translates to 'to miss' in English.

Frequently Asked Questions
Can 'perderlo' be used for a girl?
No. If you are talking about a female person or a feminine object (like 'la llave'), you must use 'perderla'.
Why is it not 'lo perder'?
In Spanish, if the verb is in its basic infinitive form, the pronoun 'lo' must either go before a conjugated verb or stick to the end of the infinitive. 'Perderlo' is the correct way to attach it.
