Morphology

noctambulism = noct + ambul + ism

The parts correspond to 'night' + 'walk' + a nominalizing '-ism', but the combining forms ('noct-','ambul-') are not productive or familiar to an average B1 learner, so the meaning is only partially derivable.

Etymology

Noctambulism breaks into noct- 'night' and -ambul- 'walk', the same root as the simple word amble. So it literally means 'walking at night' and describes walking while asleep, or 'sleepwalking'.
