+ '''genius''' ''m'' (genitive geniī or genī); second declension^(Wiktionary)
+
+ ==Etymology==
+ It is derived from the root of [[gigno|alt=gignere]] “to beget”, [[ine-pro|*ǵenh₁-|t=to beget]], perhaps through the Old Latin present [[m|la|genō]], with the suffix [[m|la|-ius]].^(OLD 2012)^(Wiktionary)^(Etymonline) Its original sense was thus the generative power, or inborn nature.^(Etymonline)^(Georges 1913) The OLD compares Germanic words for “kin”, such as [[goh|chunni]] and [[ang|cynn]].^(OLD 2012) It is not related to [[ar|جِنِّيّ|tr=jinnī|t=jinn]].^(Wiktionary)^(Etymonline)
+
+ ==Earliest recorded meaning==
+ It is found from Plautus onwards,^(de Vaan 2008)^(Köbler 2010) who mentions a man sacrificing to his [[m|en|genius]] and uses the oath ''per tuum te genium obsecro'' “I beseech you by your genius”.^(OLD 2012)
+
+ ==Semantic evolution==
+ The OLD defines it as the male spirit of a family (''gens''), living in its head and then in the divine part of each person, and Horace calls it the companion who rules one's birth star.^(OLD 2012)^(Lewis & Short 1879) Since one celebrated one's genius on birthdays and festivals, it came to stand for one's appetites, as in ''genium curare'' or ''indulgere genio'' “to indulge oneself”, and a parasite might call his patron ''genius meus''.^(OLD 2012)^(Georges 1913) Gods, places, cities and corporations had their genius, as in ''genius loci'', and the genius of the emperor was an object of worship.^(OLD 2012)^(Lewis & Short 1879)
+
+ From innate nature it passed to talent and inspiration in writing.^(OLD 2012)^(Wiktionary) In medieval Latin it meant splendour and character.^(Niermeyer 1976) English borrowed it in the late 14th century for a guardian spirit, and the senses “characteristic disposition” and “person of great talent” developed later; through French ''génie'' it also gave [[en|genie]].^(Etymonline)
