Surface Forms

Morphology

up + to + some + devilment

The sense 'engaged in mischievous activity' is directly derivable from combining the construction 'be up to' (meaning 'doing/engaged in') with 'devilment' (mischief). This composition follows a standard English pattern and has clear cross-linguistic parallels, so a B1 learner who knows the constituent meanings would understand the MWE.

Etymology

Up to some devilment may come from the image of little 'devils' hiding and planning naughty tricks. Here up to means 'doing' and devilment means naughty mischief, so the phrase now means 'doing mischief'.
