The story
- Old Persian · derived from*Vidāspaʰ
- Sanskrit · derived fromवितस्ता
- Ancient Greek · derived fromὙδάσπης
- Latin · borrowed fromHydaspēs
- English todayHydaspes
Borrowed from Latin Hydaspēs, from Ancient Greek Ὑδάσπης (Hudáspēs), itself from Sanskrit वितस्ता (vitastā), also proposed to have been borrowed from Old Persian *Vidāspaʰ (literally “caring for horses”), from *vīd- (“to take care of”) + 𐎠𐎿𐎱 (a-s-p, “horse”) to explain the development -sp- instead of -st-, but this has no basis in any attested names for the river.
