Morphology

froth + at + the + mouth

The idiomatic meaning 'to be extremely and uncontrollably angry' is directly derived from the literal image of someone foaming (froth) at the mouth, so a learner who knows 'froth' and 'mouth' can infer the emotional/state meaning from the parts. This locative action + body-part composition is a transparent, metaphorically motivated extension that is common cross-linguistically, so a B1 learner familiar with the constituents should be able to understand it.

Etymology

The idiom froth at the mouth comes from seeing animals that are very angry or ill and have froth around their mouths. People used that strong image to describe someone so furious they seemed out of control, so the phrase now means 'to be extremely and uncontrollably angry'.
