'representationalness' originates from English, formed by adding the suffix '-ness' to the adjective 'representational', where 'representational' ultimately derives from Latin 'repraesentare' meaning 'to present again'.

'representationalness' is a modern English abstract noun built from 'representational' (adjective) + '-ness'. 'Representational' developed from Middle English forms of 'represent' (from Old French 'representer'), which in turn comes from Latin 'repraesentare' (re- 'again' + praesentare 'to place before, present').

The Latin root originally meant 'to present again' (literal presentation or making present); over time the sense shifted through 'to depict' or 'to stand for', and the modern formation 'representationalness' denotes the abstract quality of being representational.
