+
+ ==Etymology==
+ It is [[inh|itc-pro|*pwījo-]], [[inh|ine-pro|*puH-yo-|t=purifying]], from the root [[ine-pro|*pewH-|t=to purify]] of [[pūrus]] “pure”.^(de Vaan 2008)^(Wiktionary)^(Etymonline) Cognate with [[osc|piíhiúí|t=pious (dative)]], [[xum|pihaz|t=purified]] and Paelignian and Volscian forms.^(de Vaan 2008)^(OLD 2012)^(TLL) The first syllable is short in Old Latin poetry, and the development from *puH-yo- is disputed: Schrijver and Meiser follow Thurneysen's rule of umlaut, while others posit *pwījo-.^(de Vaan 2008)^(TLL)
+
+ ==Earliest recorded meaning==
+ Köbler's first source is Ennius, and de Vaan dates it from Plautus.^(Köbler 2010)^(de Vaan 2008) Köbler dates Ennius 204–169 BC.^(Köbler 2010)
+
+ ==Semantic evolution==
+ It meant faithful to one's moral obligations, dutiful, conscientious, upright, and of the virtuous dead blessed, as Horace's pious souls.^(OLD 2012) It was used of just conduct, of a just war, and above all of faithfulness to religious duties, devout, as Plautus' gods who favour the pious, and of sacred offerings, as Horace's pious offering of grain.^(OLD 2012) Of family it meant devoted to parents, spouse or relatives, as Plautus' chaste and loyal wife, and Cicero says the country gains from citizens dutiful to their parents.^(OLD 2012) ''Pius'' was an honorific cognomen, given to Quintus Metellus and to the emperor Antoninus in AD 138, and Cicero condemned the superlative ''piissimus'' as not Latin.^(OLD 2012)
+
+ In Christian and Medieval Latin it meant pious, holy, saintly, and devout towards God.^(Niermeyer 1976)^(DMLBS) It survives in Italian ''pio'' and French ''pieux''.^(Wiktionary) [[en|pious]] was borrowed in the mid-15th century, and [[en|piety]] and [[en|pity]] come from [[pietās]].^(Etymonline)
