Surface Forms

Morphology

snake + in + the + grass

The image of a 'snake' hidden 'in the grass' yields a clear metaphor of concealed danger or treachery, so a learner who knows the words can plausibly infer a meaning like a hidden/deceitful person. However, the interpersonal sense (someone who pretends to be friendly but is treacherous) is a figurative, culturally conventionalized extension and not strictly compositional, so full understanding often requires prior exposure.

Etymology

The idiom snake in the grass comes from the picture of a snake hiding quietly in grass, looking harmless until it strikes without warning. That's why the phrase means 'a person who pretends to be friendly but is actually deceitful or treacherous'.
