Amazonian adj.

late 14c., "one of a race of female warriors in Scythia," via Old French (13c.) or Latin, from Greek Amazon (mostly in plural Amazones), probably from an unknown non-Indo-European word, or possibly from an Iranian compound *ha-maz-an- "(one) fighting together" [Watkins]. But in folk etymology it has been long derived from a- "without" + mazos, variant of mastos "breast;" hence the story that the Amazons cut or burned off one breast so they could draw bowstrings more efficiently.

It was also used generally in early Modern English of female warriors; strong, tall, or masculine women; and the queen in chess.

The river in South America (originally called by the Spanish Rio Santa Maria de la Mar Dulce) was rechristened with this name by Francisco de Orellana, 1541, after an encounter with female warriors of the Tapuyas (or, as some say, beardless, long-haired male tribesmen). Others hold that the river name is a corruption of a native word in Tupi or Guarani meaning "wave."

variant of suffix -an (q.v.), with connective -i-. From Latin -ianus, in which the -i- originally was from the stem of the word being attached but later came to be felt as connective. In Middle English frequently it was -ien, via French.
