Morphology
orthophosphoric + acid
This is a straightforward adjective + noun composition: the modifier 'orthophosphoric' specifies a subtype of 'acid', so a learner who knows the constituents can infer it denotes a specific chemical acid (H3PO4). The naming pattern (type-of + acid) is compositional and cross-linguistically common, making the meaning predictable even if the term is technical.
Etymology
Orthophosphoric acid comes from the part ortho, meaning 'straight' or 'normal', and phosphoric, named after phosphorus, the element linked to its phosphate part. So the name points to the common, or 'normal', form of phosphoric acid found in foods, drinks, and fertilizers.
