right-angledness
|right-ang-gled-ness|
/ˌraɪtˈæŋɡəldnəs/
having a right angle
Etymology
'right-angledness' is a modern compound formed from 'right-angled' + the nominalizing suffix '-ness'. 'right' originates from Old English 'riht' meaning 'straight' or 'correct', and 'angle' originates from Latin 'angulus' meaning 'corner'.
'right' comes from Old English 'riht'; 'angle' comes from Latin 'angulus' via Old French and Middle English ('angle'); the adjective 'right-angled' arose by combining 'right' + 'angled' (having an angle of 90°), and modern English formed the abstract noun 'right-angledness' by adding the Old English-derived suffix '-ness'.
Initially the components meant 'straight/correct' ('right') and 'corner' ('angle'); combined they meant 'having a right (90°) angle' and this literal geometric meaning has been retained in the compound noun 'right-angledness'.
