geography: [16] All the English ‘geo-’ words (geography, geology [18], geometry [14], etc) come ultimately from Greek gē ‘earth’, a word probably of pre-Indo-European origin, whose Homeric form gaia was used as the name of the Greek goddess of the earth. Geography denotes literally the ‘describing of the earth’; geometry the ‘measuring of the earth’ (from its early application to the measuring of land and surveying). => geology, geometry
