analogue
UK: ˈænəlɒɡ | US: ˈænəlɔːɡ
n. something that is similar or comparable to something else
n. (biology) an organ or structure similar in function but different in evolutionary origin
adj. relating to or using signals or information represented by continuously variable physical quantities
The word "analogue" originates from Greek analogos ("proportionate"), combining ana- ("according to") and logos ("relation"). It entered English via Latin analogus and French analogue, initially describing mathematical proportionality. Over time, it broadened to signify functional or structural similarity, especially in biology and technology (e.g., analogue vs. digital signals). The morphemes reflect a logical progression from "comparative reasoning" to "parallel representation."
