Usage notes and common mistakes
Be aware of differences between verbs and constructions to avoid confusion.
Do not use perder to mean simply forgetting in every case; it implies losing something permanently. Use olvidar or dejar for forgetting or leaving behind.
Remember reflexive form: Me olvidé is very common in spoken Spanish for I forgot.
For past participle, He olvidado emphasizes the completed action with present relevance. Use the simple past Olvidé when narrating a past event.

Muchas gracias por tu ayuda. — Thank you very much for your help.
Te lo agradezco. — I appreciate it.
Mil gracias, perdón por las molestias. — Thanks a lot, sorry for the trouble.
