Morphology
peter + out
The core verb 'peter' has no transparent, productive meaning for most learners (it is historically a name-derived verb) so knowing 'peter' + 'out' does not allow a B1 learner to infer 'gradually diminish'. The particle 'out' only suggests an end or disappearance but does not supply the specific sense, making the expression idiomatic and unpredictable.
Etymology
The idiom peter out brings to mind a small flame or stream that slowly gets smaller until it stops. So, it means 'to gradually become weaker, smaller, or end'.
