Etymology
Origin of analogue
1820–30; < French < Greek análogon, neuter of análogos analogous; replacing earlier analogon < Greek
Explanation
Think of analogue as referring to something parallel or comparable to something else. For example, a lobster's claw might be considered an analogue to the human hand, as both have similar functions of grabbing and holding. Keep your claws to yourself! The word analogue (also spelled analog) comes from the Greek ana, meaning "up to," and logos, meaning, among other things, "ratio" and "proportion." In 1946, it entered computer language as an adjective to describe a type of signal that is continuous in amplitude. It has since been largely replaced by a digital signal. Analogues are often used in college entrance exams, i.e., "a is to b as c is to d."
