Questions & Answers about Anoche extravié mi llavero rojo.
What is the difference between extraviar and perder?
Why is extravié in the preterite tense here instead of the imperfect?
How would I use this lesson's grammar topic to say 'Maybe I misplaced my red keychain last night'?
You would simply say: A lo mejor anoche extravié mi llavero rojo. When you use a lo mejor to express probability, it is almost always followed by a normal indicative verb (like the preterite extravié) rather than the subjunctive mood, making it a very beginner-friendly phrase to use!
