Albatross
The name albatross came from the Arabic word al-câdous or al-ġaţţās. This means a pelican, or can mean "the diver". This word later became English, also mixed with the Portuguese word alcatraz, which means "gannet". This is also where the name of the prison Alcatraz comes from. The OED explains that the word alcatraz was at first supposed to be used for the frigatebird. But perhaps the change of the word to albatross was because of the Latin word albus. This means "white", which is opposite to the frigatebirds which are black. In Portuguese, the word still presently used for the bird, albatroz, came from the English albatross.
