'artificialness' originates from English, specifically formed from the adjective 'artificial' plus the noun-forming suffix '-ness', where 'artificial' ultimately comes from Latin 'artificialis' (from 'artificium'), and in those Latin roots 'ars/art-' meant 'skill' or 'art' and 'facere' meant 'to make.'

'artificial' entered English via Old French 'artificiel' and Middle English forms (e.g. 'artifissial'/'artificial'), and later the productive Old English suffix '-ness' was added to form 'artificialness'.

Initially it meant 'made by skill or art' (i.e. produced by human craft), but over time the sense broadened and often took on 'not natural' or 'insincere' connotations; the modern meaning covers both being human-made and the lack of genuineness.
