Borrowed from Nepali तराइ (tarāi) and/or Hindustani (Hindi तराई (tarāī) / Urdu ترائی (tarāī, “marsh, foothills”)), from Prakrit *तलघट्टिका- (*talaghaṭṭikā-), ultimately derived from Proto-Indo-Aryan *taras (“plain, plateau”), possibly related to Sanskrit तल (tala, “level”); cognate to Nepali तराइ (tarāi). Possibly later associated with Classical Persian تر (tar, “humid”).

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
