Forms
informer[1] Old French enformer, infourmer and einformer.[2][3] Anglo-Norman spellings include enfourmer, enfurmer and efformer.[4]
Etymology
It is inherited from Old French enformer (“to give a form to”), inherited from Latin īnfōrmō (“to shape, form, represent in the mind”), refashioned after the Latin word in the 15th century.[3][2][5][6][7] That verb is formed from Latin in- + fōrmō (“to form”), from fōrma (“form”).[3][6] Wiktionary treats the modern verb as borrowed from Latin.[1] The refashioning wavered in its form and prefix, as in infourmer (1286) and einformer (1351).[3][2]
Compare Occitan informar, Spanish informar and Italian informare.[8] The English verb inform (early 14th century) comes from the Old French verb and directly from Latin.[9]
Earliest recorded meaning
As enformer it is first recorded in 1174, in Guernes de Pont-Sainte-Maxence's life of Thomas Becket, meaning “to give a form to”.[2][3] Littré quotes from that text pur la pais enformer “to make the peace”.[8]
Semantic evolution
The Old French verb also meant “to instruct someone in something” (1275).[3] The refashioned verb was first reflexive, soi infourmer “to inquire” (1286), then transitive, “to let someone know” (1351), and informer que “to tell someone that” is found in 1392.[2][3] In 1538 it took the legal sense “to conduct a criminal investigation”.[2][3]
In the 16th century it took up again the Latin sense “to give a form to” (1567, Philibert de l'Orme), especially in philosophy, of the soul giving organised life to a body (1572, Amyot) and later of a spiritual principle (1617).[2][3] The sense “to question someone about something” (before 1615) did not last.[3] In the 20th century the verb was influenced by the newer senses of information.[3] In law, the past participle used as a noun gave un plus ample informé (1671) “a fuller inquiry”, whence jusqu'à plus ample informé.[3]
