piscine (French)

Where does "piscine" come from?

The French noun 'piscine' derives directly from the Latin word 'piscīna', which referred both to a fishpond and to a swimming pool[1]. This term was originally formed within Latin by attaching the suffix '-īna' to 'piscis', meaning 'fish', to indicate something characterized by fish[1][2]. Tracing back further, 'piscis' came through Proto-Italic '*piskis' from the Proto-Indo-European root '*peysk-' or '*péysks'[1][4][5].

Open questions

• The ultimate Proto-Indo-European root is geographically limited to Western Indo-European languages, leading to theories that it might be a borrowing from an unknown substrate language. [3]
• Linguists debate alternative reconstructions for the root, including derivations meaning something painted or spotted, something nourishing, or something finned. [3]
