early 13c., "made of earth;" see earth (n.) + -en (2). Not attested in Old English (where eorðen meant "of or in the earth"). Cognate of Old High German irdin, Dutch aarden, Gothic airþeins. Meaning "made of clay" is attested from late 14c.
"manufactured goods, goods for sale," Old English waru "article of merchandise," also "protection, guard," hence probably originally "object of care, that which is kept in custody," from Proto-Germanic *waro (source also of Swedish vara, Danish vare, Old Frisian were, Middle Dutch were, Dutch waar, Middle High German, German ware "goods"), from PIE root *wer- (3) "perceive, watch out for."
Usually wares, except in compounds such as hardware, earthenware, etc. Lady ware was a jocular 17c. euphemism for "a woman's private parts" (but sometimes also "male sex organs"), and Middle English had ape-ware "deceptive or false ware; tricks" (mid-13c.).
