ᴱ√LIÞI root. “*flow of time”
A root for various words in the Gnomish Lexicon of the 1910s having to do with the flow of time, such as G. lith- “go, depart, be over, finish, end, die”, G. lithin “bygone, ended”, and G. lint “quick, agile, nimble, light” (GL/54), as well as G. laith “time, the course of time; lapse”, and G. laith(r)a- “let slip, lose, mislay, forget; (intr.) to be lost” (GL/52). The last of these was “a confusion of two distinct roots — see lech and lith-”, referring to ᴱ√lech “smooth, slippery” whose derivatives included laitha- “slip (intr.), slide by” (GL/53).
