Darkolândan, from dar-, → in-, + kolândan "to shut," from kolân "wooden bolt, latch;" variants kelân, kolun, kolum, koland, kolandân, kelid, kelidân "wooden bolt, latch;" kalâk "a crook stick for gathering fruit;" (Tabari) kali, (Lori) kelil, (Laki) kalil "key; lock;" (Kurd.) kilil, kilij "key;" (prefixed) biškal(a) "a crooked stick for opening a lock, a sort of key;" (Kurd.
