PIE word
*tréyes
Borrowed from Hindi तिपाई (tipāī), Urdu تپائی (tipāi, “teapoy”), from a merger of Sanskrit त्रिपाद (tripāda, “tripod”) + Classical Persian سه پای (sih-pāy, “tripod”), with the spelling of the first element influenced by association with tea. Sanskrit त्रि (tri, “three”), the first element of त्रिपाद (tripāda), is ultimately derived from Proto-Indo-European *tréyes (“three”); while Classical Persian پای (pây, “foot”), the second element of سه پای, is ultimately from Proto-Indo-European *pṓds (“foot”), from *ped- (“to step; to walk; to fall; to stumble”). Doublet of tripod and tripus.
