Morphology

hypophosphoric + acid

This is a specialized chemical name where the modifier 'hypophosphoric' is not a common lexical item and has no accessible definition provided; a B1 learner who only knows the word 'acid' would not be able to recover the specific chemical identity or properties from the parts. Even recognition of the prefix 'hypo-' or root 'phosphor-' would not yield the precise meaning (a tetrabasic reducing acid), so the expression is not transparently compositional for learners at that level.

Etymology

Hypophosphoric acid comes from the parts hypo-, which means 'less', and phosphoric, from 'phosphorus'. The name gives a simple image: it is a different kind of phosphoric acid with fewer oxygen atoms and two phosphorus atoms in each molecule, so chemists use this special name to show it is not the usual phosphoric acid.
