fors f (genitive fortis); third declension[1]
Etymology
It is inherited from Proto-Italic *forti- (“luck”), perhaps from Proto-Indo-European *bʰr̥-ti- (“bearing, what is brought”), from the root of ferō “to bear”.[2][1][3] Cognate with Sanskrit भृति (bhṛtí, “support”), Old Irish brith (“birth”) and English birth.[3][1][4] fortūna is its derivative.[5][6]
Earliest recorded meaning
De Vaan dates it from Plautus, Köbler from Ennius.[2][7] Köbler dates Plautus c. 250–184 BC.[7]
Semantic evolution
It was chance or luck seen as directing events, the lot that attaches to a thing, a chance happening, and with a genitive the chance of doing something.[3] It was used almost only in the nominative and in the ablative forte “by chance”.[2][8] Phrases with fors gave adverbs “perhaps”: fors sit an gave forsitan, and fors itself was used as an adverb in Virgil and Horace.[2][3] Cicero says “let chance see to these things”.[8]
Medieval writers used it for fate, glossed by Old English wyrd.[9] Its derivative fortuītus gave English fortuitous in the 1650s, and fortūna gave English fortune about 1300.[6]

Usage notes
Döderlein contrasts cāsus, chance as a blind natural agent, with fors, chance pictured almost as a being that toys with mortals, and with fortūna, fortune that is not blind.[10]
