Morphology

hyponitrous + acid

This is a specialized chemical name: while 'acid' is a familiar word, 'hyponitrous' is a technical morphological formation (hypo-/nitrous) not part of everyday vocabulary and encodes specific chemical structure and properties. A B1 learner who knows only the surface constituents would not be able to derive the precise meaning (instability, formula H₂N₂O₂, explosive/rare) from the parts, so the expression is not transparently interpretable.

Etymology

Hyponitrous acid comes from the parts hypo- meaning 'less' and nitrous meaning 'from nitrogen', so the name literally says it is a 'less' or lower-oxygen form of a nitrogen acid. That helps you remember it is a rare, weak, and unstable acid that can break down suddenly and sometimes release gas or even behave explosively.
