adobe (n.)
1739, American English, from Spanish adobe "unburnt brick dried in the sun," which is said by 19c. Dutch Arabist Reinhart Dozy to be from oral form of Arabic al-tob "the brick," from Coptic tube "brick," a word found in hieroglyphics. Other sources point to a Spanish adobar "daub, plaster," from the source of English daub (v.).

photoshop (v.)
"to edit an image using a computer program," 1992, originally, and properly still, only in reference to Photoshop, a bitmap graphics editor trademarked and published by Adobe, released in 1990. Like Taser and Dumpster, it has a tendency to become generic, but if you use it that way in print their lawyers will still send you The Letter. Related: Photoshopped; photoshopping.
