Forms

assurer[1] Old French asoürer (1080, reflexive), asseürer (until the 16th century).[2][3][4]

Etymology

It is inherited from Old French asseürer, inherited from Vulgar Latin *assēcūrāre (“to make safe, protect”),[2][5][6][7] from ad- and Latin sēcūrus (“safe, secure”) (see sûr);[2][1] the verb is postulated from forms in most Romance languages.[2]

Cognate with Italian assicurare, Old Occitan assegurar and Spanish asegurar.[5][4] The Anglo-Norman “asseurer” corresponds to English assure.[8]

Earliest recorded meaning

The Chanson de Roland (about 1100) has Li quens Rolans mie ne s'asoüret, Count Roland does not seek safety: “to put (oneself) in safety”.[4][2]

Semantic evolution

In the late 12th century it took the psychological sense “to reassure, make confident”, later largely taken over by rassurer (Chrétien de Troyes, Corneille's tâchons d'assurer la Reine).[2][5][9] From the mid-12th century it also meant “to affirm as certain”: assurer qqn de qqch., assurer à qqn que (Marie de France), assurer que (1461), and the conversational je t'assure.[2][9] Old French also used it for handing over a pledged property (1305), whence s'assurer de qqch. “to secure” (1640) and s'assurer que “to make sure”.[2]

From 1486 it meant to make firm or steady, and in climbing to belay (Saussure, 1780; with a rope, 1913).[2][10] From the early 15th century ships and goods were assurés against risks, and in 1829 property in general.[2][5] Assurer also means to ensure, provide (assurer un service), and in recent slang, from musicians' use (1971), “to be up to it”.[2][11]
