Etymology
'auxochromic' originates from the adjective formed from 'auxochrome' + the suffix '-ic'; 'auxochrome' ultimately comes from Greek elements 'auxo-' meaning 'increase' and 'chroma' meaning 'color'.
'auxochrome' was coined in modern chemical nomenclature (19th century) from Greek roots ('auxo-' + 'chroma'); adding the English adjectival suffix '-ic' produced 'auxochromic' to describe the property of having or relating to an auxochrome.
Initially the roots meant 'increase' and 'color'; in modern chemical usage the combined term came to mean a substituent that increases or alters a chromophore's color properties, and 'auxochromic' now specifically describes that relating quality.
