Morphology

somnambulatory + behavior

The phrase is a straightforward adjective+noun composition: 'somnambulatory' (relating to sleepwalking) modifies 'behavior' (actions), so together they yield 'behavior involving sleepwalking or actions performed while asleep.' Although 'somnambulatory' is a low-frequency, derived term, its meaning directly composes with 'behavior', so a learner who knows both constituents can infer the MWE meaning.

Etymology

The phrase somnambulatory behavior comes from old words meaning 'sleep' (somnus) and 'walk' (ambulare). It gives a clear image of someone moving or doing things while asleep, so it is used for 'walking or acting while not awake'.
