'spiritedly' originates from English, formed by adding the adverbial suffix '-ly' to 'spirited', where 'spirited' is derived from 'spirit' meaning 'breath, courage, life'.

'spirit' comes from Latin 'spiritus' meaning 'breath' or 'spirit'; it passed into Old French as 'espirit' and into Middle English as 'spirit'. The adjective 'spirited' developed from 'spirit' + '-ed', and the adverb 'spiritedly' was formed by adding '-ly' to 'spirited'.

Originally related to 'breath' or 'soul' (literal and figurative senses of 'spirit'), the sense shifted toward 'energy, courage, liveliness', which is reflected in the modern adverb 'spiritedly' meaning 'in an energetic or forceful way'.
