From the same root
Forms
assecuro (present infinitive assecurare, perfect active assecuravi, supine assecuratum); first conjugation[1] Spellings include adsecuro, asecuro and assicuro.[2]
Etymology
It is from Latin ad- + sēcūrus (“free from care, safe”).[1][3][4] The MLW compares Italian assicurare and French assurer.[1]
English assure comes from Old French asseurer.[5]
Earliest recorded meaning
The MLW's earliest citation is from Hugo of Farfa, around 1020, who wanted to give certain people a guarantee about the castle of Tribuco.[1][6]
Semantic evolution
It began as a word of medieval law and politics: to promise on oath, in a peace treaty, to refrain from harming someone, to guarantee that another would do the same, and, in the oath of fidelity, to promise a feudal lord not to harm his person, property or honour.[7][1] From this came the senses “give a safe-conduct” to a traveller and “guarantee, warrant” a statement or a payment.[1][4][2]
More generally it meant to make someone sure or free from worry, and, reflexively, to feel sure or trust.[1][8] In Poland it was used of securing a sum of money on landed property.[4] Falconers used it of taming hawks.[1]
