salt formed with hydrochloric acid

Etymology
Etymology Information

'hydrochloride' originates from Modern English formation, specifically combining the Greek-derived prefix 'hydro-' (from Greek 'hydōr') and 'chloride' from New Latin 'chloridum', where 'hydro-' meant 'water' and 'chloros' (source of 'chlor-') meant 'green'.

Historical Evolution

'hydrochloride' changed through combination of elements: the element 'chloride' comes from New Latin 'chloridum' (via German 'Chlorid') derived from Greek 'chloros', and was joined with the Greek prefix 'hydro-' in modern chemical nomenclature to form 'hydrochloride'.

Meaning Changes

Initially, related roots referred to 'water' and the greenish aspect of chlorine ('hydro-' and 'chlor-'); over time the combined term came to specifically denote the salt formed by reaction with hydrochloric acid, i.e., the modern chemical meaning of 'hydrochloride'.
