'syncarpous' originates from New Latin/Modern Latin, ultimately from Greek elements 'syn-' meaning 'together' and 'karpos' meaning 'fruit' (used for 'carpel' in botanical formation).

'syncarpous' was formed in scientific Latin from Greek 'syn-' + 'karpos' (fruit/carpel), appearing in New/Modern Latin as 'syncarpus'/'syncarpous' and then adopted into English botanical usage.

Initially constructed to mean 'joined or together (with respect to fruit or carpels)', it has come to be used specifically in botany to mean 'having fused carpels forming a single ovary.'
