'homodont' originates from New Latin (or Modern Latin), specifically the word 'homodontus', where Greek 'homos' meant 'same' and Greek 'odous' / 'odont-' meant 'tooth'.

'homodont' changed from Greek 'homodontos' (ὁμοδόντος) into New/Modern Latin 'homodontus' and was adopted into English as 'homodont'.

Initially, it meant 'having the same kind of teeth' in technical anatomical usage, and over time it has retained this specialized meaning in biology and paleontology.
