Name of the marsh at the mouth of Sirion translated “Land of Reeds” (UT/34), a combination of lisg “reed” and the lenited form of gardh “region”.
Conceptual Development: In the earliest Lost Tales, this name appeared as G. Arlisgion “Place of Reeds” (LT2/153) and in the Gnomish Lexicon from the 1910s as G. Garlisgion (GL/67). The derivation of these early forms is quite similar to the latter one, with the order of elements reversed: G. gar(th) “place” followed by G. lisg “reed” (in the genitive plural).
A word appearing as an element in the name Lisgardh “Land of Reeds” (UT/34).
