M.E., from Medieval L. camlopardus, from L. camelopardalis, from Gk. kamelopardalis, from kamelos "camel" + pardalis, pard "leopard" (because the giraffe has a head like a camel's and the spots of a leopard), from L. pardus, from Gk. pardos "male panther," from the same source (probably Iranian) as Skt. prdaku- "leopard, tiger, snake," and Pers. palang "panther."

Zarrâfé "giraffe," from Ar. zarafa, probably from an African language. This term is at the origin of this animal's name in European languages, via It. giraffa. The Pers. name of the animal is: šotor-gâv-palang, from Mid.Pers., composed of šotor "camel" + gâv "ox, bull, cow," → Taurus, + palang "panther."

camera
  کدک   
kadak

Fr.: appareil photo, caméra   

1) An apparatus for recording the light from an object onto a sensitive material, such as film or CCD detector.
2) A device that converts optical images into electrical impulses.

Mod.L. camera obscura "dark chamber" from L. camera "vaulted room," from Gk. kamara "vault," cf. Av. kamarâ- "waist; vault" Mod.Pers. kamar "waist," Skt. kamarati "is vaulted;" PIE base *kam- "to arch."

Kadak "small room," from kad, kadé "room, chamber, habitation, vault, cell, cavern," Mid.Pers. katak, Av. kata- "(small) room, closet, (small) house," cf. Goth. hethjo "small room" O.S. kotici "cavern, nest," PIE *kot(os).

Canada-France-Hawaii Telescope (CFHT)
  تلسکوپ ِ کانادا-فرانسه-هاوایی   
teleskop-e Kânâdâ-Farânsé-Hâvâyi

Fr.: télescope Canada-France-Hawaii   

A 3.6 m optical/infrared telescope jointly owned and operated by the Canadian National Research Council (NRC), the French Centre National de la Recherche Scientifique (CNRS), and the University of Hawaii. It became operational in 1979. The observatory is located atop the summit of Mauna Kea, a 4200 m, dormant volcano located on the island of Hawaii. The Observatory headquarters is located in Waimea (also known as Kamuela by the US Postal Service). Situated at the low latitude of Hawaii (+19° 45'), there is a fairly large sky overlapping with that of the → European Southern Observatory (ESO)  → La Silla observatory (δ = -29° 15'). The point where an object is seen at the same → zenith distance from La Silla and from Mauna Kea, when it crosses the meridian, is δ =-5°. Taking into consideration also the difference in elevation between the observatories, the → declination at which one has equal air mass is moved down to δ =-18°. The extreme limit of observing from Mauna Kea is -60° (10° above horizon) but all programs below -20° are most efficiently carried out from ESO.

Canada, from the St. Lawrence Iroquoian word kanata, meaning "village" or "settlement;" France, from the L. Francia "country of the Franks;" Hawaii, named for Hawai'iloa, a legendary figure from Hawaiian mytholgy; → telescope.

Cancer,from L., from Gk. karkinos; PIE base *qarq- "to be hard" (like the shell of a crab); cf. Skt. karkatah "crab," karkarah "hard."

Xarcang "crab," from Mid.Pers. karcang, cf. Lori qerženg from kar-, qer- + cang, ženg "claw." The component xar/qer may be related to Av. xruta-, xraoždva- "hard," as in xruždisma- "hard ground" (from xruždi- + zam-), and to the PIE *qarq- "to be hard." In that case, the Pers. term for crab would literally mean "hard claw."
