lár

ear

lár (2) noun "ear" (?). Tolkien's wording is not clear, but ¤lasū is given as an ancient dual form "(pair of) ears"; Quenya lár could represent the old singular las- (LAS2). In a post-LotR source, Tolkien derives hlas "ear" (dual hlaru) from a stem SLAS(PE17:62). Initial hl- rather than l- reflects the revised form of the stem (LAS becoming SLAS), and in the later version of the phonology, postvocalic -s does not become -r when final. Compare the noun "dream", given as olor in the Etymologies (LOS), but as olos pl. olori in a later source (UT:396)

lár

league

lár (1) noun "league", a linear measure, 5000 rangar (q.v.). A ranga was approximately 38 inches, so a lár was "5277 yards, two feet and four inches [ca. 4826 m], supposing the equivalence to be exact" - close enough to our league of 5280 yards to justify this translation. The basic meaning of lár is "pause"; in marches a brief halt was made for each league. (UT:285)

lár

noun. league; †stop, pause

A Númenórean unit of measure that was translated as “league”, 5000 rangar in length or about 5277 yards, which is very close to an English league = 3 miles or 5280 yards (UT/279, 285). Its original meaning was “stop, pause” as this is the distance where forced marches usually stopped for a rest, and thus it was likely derived from the root ᴹ√DAR “stay, stop” (Ety/DAR).
