+ ==Pronunciation==
+ * IPA (Classical): [ˈmoːs]^(Wiktionary)
+ * IPA (Ecclesiastical): [ˈmɔs]^(Wiktionary)
+
+ ==Forms==
+ '''mōs''' ''m'' (genitive mōris); third declension^(Wiktionary)
+
+ ==Etymology==
+ It is [[inh|itc-pro|*mōs-]], of uncertain origin.^(de Vaan 2008)^(Wiktionary)^(OLD 2012) De Vaan derives it from [[ine-pro|*m(e)h₁-ōs|t=manner]], from *meh₁- “to measure”, since the meaning is close enough to “measure”.^(de Vaan 2008) Wiktionary reports the common view that it comes from *meh₁- “to be intent upon, of strong will”, with Greek [[grc|μαίομαι|tr=maíomai|t=to strive]].^(Wiktionary)^(TLL) Isidore calls ''mōs'' a long custom.^(Isidore)
+
+ ==Earliest recorded meaning==
+ De Vaan and Köbler date it from Naevius.^(de Vaan 2008)^(Köbler 2010) Plautus has a liar who says he will act ''meō mōre'' “after my own fashion”.^(OLD 2012) Köbler dates Naevius c. 235–200 BC.^(Köbler 2010)
+
+ ==Semantic evolution==
+ It meant a person's will or whim, as in ''mōrem gerere'' “to humour someone”, an established practice or custom, and custom in general as a guide to action, often as opposed to law, so that ''mōs maiōrum'' was the custom of the ancestors.^(Gaffiot 2016)^(OLD 2012) The ablative ''mōre'' meant “in the customary way”, and ''mōre'' with a genitive “in the manner of”.^(OLD 2012) In the plural ''mōrēs'' were the morals or character of a people or person.^(OLD 2012)
+
+ Döderlein contrasts [[cōnsuētūdō]], custom arising from habit, with ''mōs'', custom regarded as a moral rule.^(Döderlein 1874) Its derivatives [[mōrālis]] and [[mōrōsus]] gave [[en|moral]] and [[en|morose]], and [[en|mores]] was borrowed by sociologists in 1907.^(Etymonline)
+

+ * c. 235–200 BC – Naevius uses it.^(de Vaan 2008)^(Köbler 2010)
+ * c. 250–184 BC – Plautus has ''meō mōre''.^(OLD 2012)^(Köbler 2010)
+ * 190–159 BC – Terence speaks of living after another's fancy.^(Gaffiot 2016)^(Köbler 2010)
+ * mid-14th century – English ''moral'' is recorded.^(Etymonline)
