It seems that the name Fortibus was an attempt by mediaeval scribes to Latinise the name "Forz", as was their custom, by using the hypothetical ablative plural fortibus which would mean "from chances".
Tampaknya nama Fortibus adalah upaya oleh para penulis abad pertengahan untuk menglatinkan nama "Forz", seperti kebiasaan mereka, dengan menggunakan hipotetis fortibus jamak ablatif yang berarti "dari peluang".
