Old English weax "substance made by bees," from Proto-Germanic *wahsam (source also of Old Saxon, Old High German wahs, Old Norse vax, Dutch was, German Wachs), from PIE root *wokso- "wax" (source also of Old Church Slavonic voskŭ, Lithuanian vaškas, Polish wosk, Russian vosk "wax" (but these may be from Germanic).
Used of other similar substances from 18c. Slang for "gramophone record" is from 1932, American English (until the early 1940s, most original records were made by needle-etching onto a waxy disk which was then metal-plated to make a master). Waxworks "exhibition of wax figures representing famous or notorious persons" first recorded 1796.

suffix added to nouns to produce adjectives meaning "made of, of the nature of" (such as golden, oaken, woolen), corresponding to Latin -anus, -inus, Greek -inos; from Proto-Germanic *-ina- (from PIE *-no-, adjectival suffix).
Common in Old, Middle, and early Modern English: e.g. fyren "on fire; made of fire," rosen "made or consisting of roses," hunden "of dogs, canine," beanen "of beans," baken "baked," breaden "of bread;" Wycliffe has reeden made of or consisting of reeds." The few surviving instances are largely discarded in everyday use, and the simple form of the noun doubles as adjective (gold ring, wool sweater). Some are used in special contexts (brazen, wooden).
