londë noun "land-locked haven" (cf. #lóndië "harbourage"), "gulf" (TI:423). In Alqualondë "Swan-haven" (SA), "Haven of Swan" (VT45:28), Hirilondë ship-name "Haven-finder" (UT:192). In the Etymologies, londë is glossed "road (in sea), entrance to harbour" (LOD) and also "fairway" (VT45:28), i.e. a navigable channel for ships. In VT42:10, where the stem is given as LON rather than LOD, the gloss is simply "haven".
