Calenhad is described as being a small, green, treeless hill
which was slightly bigger and taller than Erelas. Calenhad was
seldom lit and its lighting during the War of the Ring indicated
great urgency. It is suggested in the Unfinished Tales that
Calenhad probably means "green space" from calen "green" and sad
(lenited to had) "place, spot". In "The Rivers and Beacon-hills
of Gondor" Tolkien suggested that the second element may be sâdh
"sward, turf".  See also - ↑ 1.0 1.1 J.R.R. Tolkien, "The Rivers
