A prefixal form of N. trî “through” in The Etymologies of the 1930s, appearing as tre- when unstressed (the norm) and tri- when stressed, though there are no examples of the latter (Ety/TER). Presumably this refers to ancient rather than modern stress.

A preposition meaning “through” in The Etymologies of the 1930s derived from ON. trī under the root ᴹ√TER(ES) “pierce” (Ety/TER), so presumably derived from ✱trē with ancient ē > ī as usual in Noldorin and Sindarin. In The Etymologies as published in The Lost Road Christopher Tolkien gave the Noldorin and Old Noldorin forms as trî and trí following the usual orthographic conventions of those languages (LR/392), but Carl Hostetter and Patrick Wynne indicated they were both trī in their Addenda and Corrigenda to the Etymologies (VT46/18).
