wiktionary
The noun is derived from Latin ovātiōnem + English -ion(suffix indicating an action or process, or the result of an action or process). Ovātiōnem is the accusative of ovātiō(“minor triumph; processional entry”), from ovō(“to exult, rejoice; to applaud”) + -tiō(suffix forming nouns relating to some action or the result of an action); [1]ovō is onomatopoeic. The English word is cognate with Italian ovazione(“(Ancient Rome) minor triumph; applause”), Middle French ovation (modern French ovation(“(Ancient Rome) minor triumph; public acclamation; applause”)), Portuguese ovação(“acclamation, ovation”), Spanish ovación(“ovation”). [1]
The verb is derived from the noun. [2]
From Late Latin ovatio(“egg-laying”) + English -ion(suffix indicating an action or process, or the result of an action or process). Ovatio is derived from ovāre(“to lay eggs”), from Latin ōvum(“egg”) [3] (possibly ultimately from Proto-Indo-European *h₂ew-(“dress; to be dressed, clothe oneself”)) + -āre.
etymonline
ovation (n.)
1530s, in the Roman historical sense, from French ovation or directly from Latin ovationem (nominative ovatio) "a triumph, rejoicing," noun of action from past-participle stem of ovare "exult, rejoice, triumph," probably imitative of a shout (compare Greek euazein "to utter cries of joy").
In Roman history, a lesser triumph, granted to a commander for achievements (such as defeat of an inconsiderable enemy, accomplished with little bloodshed), insufficient to entitle him to a triumph proper. The figurative sense of "burst of enthusiastic applause from a crowd" is attested by 1831.
