Etymology: Tamoxifen is a modern coinage, built from pieces of older chemical and Latin vocabulary rather than from any single ancient word. Its name is a blend of four parts: "trans-" (across or beyond), "amine" (a class of nitrogen-containing compounds), "oxy-" (relating to oxygen, from Greek "oxus", sharp or acid), and "phenyl" (a benzene-based group, from Greek "phainein", to show, combined with "hyle", wood or matter). Each piece names a chemical feature of the molecule, and the whole is a systematic name rather than a poetic one. The "amine" element has an unexpected ancestor. It traces back to "Ammon", the Egyptian god Amun, whose temple oracle was associated with salts of ammonia, and Latin "ammoniacus" gave English "ammonia". The suffix "-ine" came into English through Old French "-in" and Latin "-inus", so the chemist's naming habit links a modern drug to an ancient deity.

Synonyms: Nolvadex, tamoxifene
