'Aurantiaceae' originates from New Latin (Modern Latin), specifically from the combining form 'auranti-' derived from Latin 'aurantium' (orange) and the taxonomic suffix '-aceae', where 'auranti-' meant 'orange (color or fruit)' and '-aceae' meant 'family (of plants).'

'Aurantiaceae' developed through taxonomic practice in New Latin by attaching the suffix '-aceae' (used since the 19th century for family names) to a root based on Latin 'aurantium'/'aurantia', eventually forming the modern family name 'Aurantiaceae'.

Initially the root referred to 'orange' or 'orange-colored' (from Latin), but in modern usage it functions as part of a formal family name meaning 'the family associated with the Auranti- group'.
