Calben (pl. Celbin) was a term used amongst Sindar that lived in Beleriand. It was used of all Elves other than Avari, and it included the Sindar. The term was thus equivalent to the Quenya word "Eldar". After the Laegrim were recognized to be from Lindarin origin, they were included in Celbin.
Calben, 'a light person' derives from Old Sindarin *kalapende.
