Morphology

black + rat + snake

The phrase is compositionally transparent: 'black' (a color) modifies 'rat snake' (a noun compound denoting a kind of snake associated with rats), so a learner who knows the words can infer it refers to a black-colored snake of that type. This adjective + species compounding is a common and regular pattern across languages, making the meaning accessible to a B1 learner.

Etymology

Black rat snake gets its name from its look and its food: it is shiny black and often eats rats and other small animals. So the name reminds people of a big, mostly 'harmless' snake that helps control rodents.
