+ It meant the quality of being one in number, as Gellius' ''singulāris numerī ūnitās'', and of being an undivided whole, unity, as in Pliny.^(OLD 2012)^(Lewis & Short 1879) In Seneca it meant oneness of mind or action, and in Varro the sharing of a common nature.^(OLD 2012) In Celsus it meant forming a uniform whole, ''in ūnitātem coīre'' “to unite”, and in Columella sameness of appearance.^(OLD 2012)^(Gaffiot 2016)

+ In Ecclesiastical Latin it meant unity.^(Stelten 1995) Medieval Latin used it of spiritual union, the unity of the Church, and concord.^(Niermeyer 1976) [[en|unity]] came about 1300 through Anglo-French, and [[en|unit]] in the 1560s as an alteration of ''unity''.^(Etymonline)
