1º_ Tray fixed to the wall or ceiling to support cables. Also the throat for lighting that hides the lamps. 2º_ It is another name for the cardillo plant, thistle or abrojo. It can be assumed that it is a masculinized form of cajilla ("capsule") for its seed, but rather it is a dissimilation of cardillo, losing the /r/ and aspirating the /d/ that sounds like /j/.
