Questions & Answers about Mi devas konfesi, ke mi preskaŭ forgesis la bileton.
Because devas is a modal-like verb meaning must / have to, and in Esperanto it is followed by an infinitive.
So:
- mi devas = I must
- konfesi = to confess / to admit
Together:
- Mi devas konfesi = I must admit
This is very similar to English must confess or have to confess.
Not always. Konfesi can mean to confess, but in sentences like this it often works more naturally as to admit.
So although the literal sense is close to I must confess, the natural English meaning is often:
- I must admit that...
It does not necessarily imply a serious wrongdoing. It can simply introduce something the speaker is acknowledging.
