Etymology

It is inherited from Vulgar Latin *īnsignō (“to mark, point out”), written Old Galician-Portuguese ensinar and Old Galician-Portuguese enssinar in the oldest texts.[2][3][1][4] The Vulgar Latin verb took the place of Latin īnsigniō (“to put a mark on, distinguish”), from īnsignis (“conspicuous”), built on signum (“mark, sign”).[2][3][5][6] Wiktionary derives it from signō (“to mark”), and notes that the form is also found in Medieval Latin.[1] Nascentes explains the sense “to teach” from “to engrave a sign, to point out”, and notes that the word replaced the Latin verb doceō.[5] In this semi-learned word the /g/ of ⟨gn⟩ fell, as in sino from the same Latin noun, instead of becoming the ⟨nh⟩ of popular words.[7]

The same Vulgar Latin verb is Galician ensinar, Spanish enseñar, Catalan ensenyar, Occitan ensenhar, French enseigner, Italian insegnare and Romanian însemna, which means “to mean” in Romanian.[8][1] French had the sense “to make known by a sign” from 1050 and “to instruct” from about 1165.[9]

Earliest recorded meaning

The Cantigas de Santa Maria use the verb for teaching: people went to ask that he should teach them the truth (que a verdad'enssinar / lles fosse), and a friar taught someone a verse very quickly (o vesso muit'agỹa que ll'o frad'enssinou).[4] The Crónica Troiana keeps the older sense “to point out”: todos nos ensinaran con o dedo “everyone would point at us with their finger”.[4]

Semantic evolution

Cunha dates ensinado and ensinamento to the 13th century, ensinança and ensino to the 14th and ensinador to the 15th.[3] The early dictionaries gloss the verb with Latin doceo and erudio, and Barbosa (1611) adds ensinar publicamente “to teach in public”, a teacher's profession.[10][11] Morais (1813) records the training of horses and dogs (cavallo ensinado), the sense “to teach a lesson, chastise” and the sense “to show” the way.[12] Figueiredo marks “to inspire” as obsolete.[13] The senses “to punish” and “to show” are still in the modern dictionaries.[14][15][16]
