Surface Forms

Morphology

devil + in + disguise

The meaning is directly built from 'devil' (an evil being) combined with 'in disguise' (having a concealed appearance), so the idea 'appears harmless but is actually dangerous/evil' is transparently derivable from the parts. This noun + prepositional phrase composition is cross-linguistically common, so a B1 learner who knows the constituents will very likely infer the correct meaning.

Etymology

The phrase devil in disguise may come from old stories where the devil hid under a disguise and looked like a normal person to trick others. That's why it now means someone who seems 'friendly' but is actually 'dangerous' or 'evil'.
