γεωμέτρης

Forms

γεωμέτρης (geōmétrēs) m (genitive γεωμέτρου); first declension^[1] Doric γεωμέτρας (geōmétras).^[2]

Etymology

A compound of γεω- (geō-, “earth”), from γῆ (gê), and μετρέω (metréō, “to measure”), with the agent suffix -ης (-ēs): “one who measures the earth”.^[1][3][4] Debrunner discusses it among compounds of this type.^[5]

Earliest recorded meaning

It is first found in Xenophon's Memorabilia and in Plato, meaning a geometer, someone who practises geometry,^[6][3] Plato's Theaetetus calls Theodorus of Cyrene by this name.^[6][7][3]

Semantic evolution

Despite its literal meaning, the word was used in Classical Greek almost only of the mathematician,^[7][3] and Plato and Aristotle set the geometer beside the arithmetician and the astronomer.^[7][3] From Menander on it also meant a teacher of geometry, and inscriptions record such teachers in gymnasia.^[7] The older sense, a land-surveyor, is found in a Doric form in the Heraclean tables and in Egyptian papyri from the 3rd century BC to the 4th century AD.^[7][8]

It passed into geometres and into Coptic, where it is attested about AD 500.^[9][10] English geometer (late 15th century) comes from the Latin word.^[11] Modern Greek γεωμέτρης (geométris) is a learned revival of the ancient word.^[12]
