Morphology

boric + acid

The term is compositionally built from 'boric' (relating to boron) + 'acid' and thus denotes an acid associated with boron; the meaning is directly derivable from the constituents. Although it is a technical chemical term, the morphological logic is predictable and used cross-linguistically in chemical nomenclature, so a learner who knows both parts will understand it.

Etymology

Boric acid comes from boric, a word linked to the substance 'boron' and the mineral 'borax' where it was first found. Because people used this mild acid for small medicines and to kill insects, boric acid now means the weak, gentle acid used as an antiseptic and insecticide.
