'Anthea' originates from Greek, specifically the word 'Antheia' (Ανθεία), where 'anthos' meant 'flower'.

'Anthea' changed from the Ancient Greek epithet 'Antheia' and entered English via Latinized and later revival forms, eventually becoming the modern English given name 'Anthea'.

Initially, it meant 'blooming' or 'flowery', but over time it evolved into its current use as a female given name meaning 'flower'.
