Word History

Etymology

epigynum Latinization of earlier epigyne, borrowed from New Latin epigynē, from epi- epi- + -gynē, feminine of -gynos, -gynus "situated (in a specified place) in relation to a female organ," borrowed from Greek -gynos "relating to or having (such or so many) wives," derivative of gynḗ "woman, wife" — more at queen entry 1

Note: The New Latin term was apparently introduced by the Swedish arachnologist Tamerlan Thorell (1830-1901) in "Recensio critica aranearum Suecicarum, quas descripserunt Clerckius, Linnaeus, De Geerus," Nova Acta Regiae Societatis Scientiarum Upsaliensis, seriei tertiae vol. II (1856-58), p. 71.
