+ ==Forms==
+ '''equus''' ''m'' (genitive equī, feminine equa); second declension^(Wiktionary)
+
+ ==Etymology==
+ It is [[inh|itc-pro|*ekʷo-]], [[inh|ine-pro|*h₁eḱ-u-|t=horse]].^(de Vaan 2008) Following Kloekhorst, de Vaan takes the Anatolian forms to show an original u-stem, which the other branches turned into the thematic [[m|ine-pro|*h₁éḱwos]].^(de Vaan 2008)^(Wiktionary) In Latin the old paradigm must have had a nominative *ekos and a genitive *ekwī, and the stem equ- was generalised from the oblique cases.^(de Vaan 2008) The spelling ⟨quu⟩ replaced earlier ⟨quo⟩ and ⟨cu⟩ after the Augustan age, on the model of the oblique cases.^(Wiktionary)
+
+ It is cognate with [[xve|ekvon]] (accusative), [[xtg|epo-]], [[sga|ech]], [[sa|अश्व|tr=áśva-]], [[grc|ἵππος|tr=híppos]], [[ang|eoh]], [[non|jór]] and [[lt|ašvíenis|t=stallion]].^(de Vaan 2008) The TLL called the change seen in the Greek form not yet clear.^(TLL)
+
+ ==Earliest recorded meaning==
+ De Vaan dates it from Livius Andronicus (280/260–before 200 BC).^(de Vaan 2008)^(Köbler 2010) The OLD's first quotation is from Ennius, of a horse that "often won at Olympia in the last lap".^(OLD 2012)
+
+ ==Semantic evolution==
+ Besides the horse in general it could mean a stallion, as opposed to the mare ''equa''.^(OLD 2012)^(Georges 1913) Poets gave horses to the Sun and Night and even to the winds.^(OLD 2012) ''Equus fluviātilis'', "river horse", was the hippopotamus.^(OLD 2012) The ''equus pūblicus'' was the horse provided by the state to a Roman cavalryman and later the mark of the equestrian order, which could be taken away for misconduct.^(OLD 2012) It also named a statue of a horse, above all the Trojan Horse, a horse-shaped standard, and the constellation Pegasus.^(OLD 2012) In late Latin ''equī pūblicī'' were post-horses,^(Lewis & Short 1879) and in medieval Latin ''equus'' was especially the war-horse.^(Niermeyer 1976)
