Etymology
The word 'lactic' is a modern scientific term derived from the Latin root 'lac, lact-', meaning 'milk'. The suffix '-ic', of Latin origin via French, is used to form adjectives meaning 'of or pertaining to'. The term was coined in the late 18th century to describe an acid first isolated from sour milk, logically connecting the substance directly to its source. Thus, the literal construction 'pertaining to milk' accurately describes its modern chemical and biological associations.
