Pronunciation

  • Classical: [kõːˈfoːr.moː][1]
  • Ecclesiastical: [koɱˈfɔr.mo][1]

Forms

cōnfōrmō (present infinitive cōnfōrmāre, perfect active cōnfōrmāvī, supine cōnfōrmātum); first conjugation[1]

Etymology

It is from Latin con- (“with, together”) + fōrmō (“to form, shape”),[2][3][1] and fōrmō is from fōrma (“form, shape”).[1] The origin of that noun is unclear; de Vaan thinks it and Ancient Greek μορφή (morphḗ, “form, shape”) may have been borrowed from a third language.[4]

Earliest recorded meaning

The TLL finds it from Afranius on,[3][5] in a comedy where someone orders that a girl be looked after and properly decked out (puellam cūrent, cōnfōrment probē).[2][3]

Semantic evolution

Lewis and Short note that Cicero uses it several times and that it is otherwise very rare in the classical period.[6] Cicero has it of nature shaping people for greater things, of speech shaped by the arrangement of words, and of training character;[2][7] in a letter he says he adapts himself to the will of a man from whom he cannot honourably dissent (ipse mē cōnfōrmō ad eius voluntātem).[2][3] Vitruvius describes the sky as shaped by the stars and their courses,[2] and Gellius says a she-bear shapes its cub by licking it.[7]

Christian writers used it for being shaped after a model: the Vulgate has nōlīte cōnfōrmārī huic saeculō, “do not be conformed to this world” (Romans 12:2), and Ambrose and Augustine write of conforming oneself to Christ or to God.[3] Ecclesiastical Latin also used it for educating.[8] English took it over in the 14th century as conform, partly through Old French.[9]
