'intuitiveness' originates from Latin, specifically the verb 'intueri', where 'in-' meant 'in/on' and 'tuēri' meant 'to look at' (via Late Latin/Old French forms that produced 'intuition' and then English 'intuitive' + suffix '-ness').

'intuitiveness' changed from the Latin root 'intueri' to Late Latin/Medieval Latin forms such as 'intuitionem' and Old French 'intuition', then into English as 'intuition' and the adjective 'intuitive' (formed in modern English), and finally the noun 'intuitiveness' by adding the suffix '-ness'.

Initially related to 'looking at' or a form of immediate perception (from 'intueri'), it evolved to mean 'immediate understanding without conscious reasoning' and now also denotes how easy something is to use or understand ('the quality of being intuitive').
