'antichloristic' originates from Modern English, specifically formed from the prefix 'anti-' (from Greek anti- meaning 'against'), the combining form 'chlor-' from Greek 'khlōros' (originally meaning 'pale green' and later used in the name 'chlorine'), and the adjectival suffix '-istic' (forming adjectives meaning 'relating to' or 'characterized by').

'antichloristic' was created in Modern English by combining 'anti-' + 'chlor-' + '-istic'. The element 'chlor-' comes from Greek 'khlōros' meaning 'pale green'; the term 'chlorine' was coined in the early 19th century for the chemical element and gas, and later gave rise to related formations in English such as 'chlorination' and derived adjectives.

The Greek root 'khlōros' initially referred to a pale green color; over time it became associated with the chemical element 'chlorine' (named for its greenish gas). In Modern English formations like 'antichloristic', the focus shifted from 'green' to 'chlorine' (and practices involving chlorine), so the compound now means 'against chlorine/chlorination'.
