A town in Gondor (LotR/790), translated “Greenham” (RC/537). The initial element is clearly calen “green”, and the final element may be the lenited form bel of pêl “fence” (as suggested by David Salo, GS/371).

Conceptual Development: In Lord of the Rings draft maps from the 1940s, this name was first given as N. Caerost before changing to Calembel (WR/437). Earlier in Lord of the Rings drafts, the name N. Calembel was used for the location that was eventually called Parth Galen (TI/382).

Early name for the town S. Calembel in Lord of the Rings drafts from the 1940s (WR/437). Its final element appears to be ost “city, town”, but the meaning of its initial element is unclear. Roman Rausch suggested that it might be caer¹ “ten” or some derivative of ᴹ√KAY “lie down” (EE/3.45). It might also be caer² “flat isle” appearing in linguistic notes around the same period (PE22/126).

See S. Calembel for further discussion.
