Forms

certitude f (plural certitudes)[1]

Etymology

It is borrowed from Late Latin certitūdō (“certainty, conviction”), which in Christian Latin meant especially the certainty of faith.[2][3] The Late Latin noun is derived from Latin certus (“sure, certain”), the source of certain.[2][4][5]

Cognate with Old Occitan sertetut, Catalan certitud, Spanish certidumbre and Italian certitudine.[6] Littré notes that Old French had said certaineté instead, a word he regretted to see fall out of use.[6]

Earliest recorded meaning

It is first recorded about 1375 in Nicole Oresme's treatise on the invention of money, in the objective sense “the quality of being certain, assured, beyond doubt”: la certitude du poix, the reliability of a coin's weight.[2][3]

Semantic evolution

The objective sense (the certainty of a fact) came first; the subjective sense, a state of mind free of doubt, a conviction, is recorded from 1462.[2][3] By extension the word also came to mean a thing that is certain, a sure fact.[7] In philosophy it names the mind's assent when it knows, as opposed to belief or opinion.[8][6]

A metaphorical term of the graphic arts, recorded in 1757, used it for the firmness of the hand guiding the burin, the point or the brush.[2][6] The older sense “assurance, guarantee” of something survives only rarely in literary use.[2]

The English word certitude was taken in the early 15th century from the Old French word and directly from Late Latin.[9]
