'bardiness' originates from English, specifically the word 'bard' combined with the suffix '-ness', where 'bard' meant 'poet' and '-ness' meant 'state or quality'.

'bard' originates from Old Irish 'bard' (meaning 'poet'), entered Middle English via contact with Celtic languages and Scots, and the modern English noun 'bard' later formed the abstract noun 'bardiness' by adding the English suffix '-ness'.

Initially, 'bard' meant 'poet' and referred to a traditional minstrel; over time the root retained its poetic meaning while compounds like 'bardiness' came to denote the abstract quality of being bard-like or poetic.
