'attitudinal' originates from English, specifically the word 'attitude' plus the adjectival suffix '-al' (ultimately from Latin '-alis'), where 'attitude' came via French 'attitude'.

'attitudinal' changed from the English noun 'attitude' (borrowed from French 'attitude' and Italian 'attitudine'), which ultimately derives from Latin 'aptitudo'; English then formed the adjective by adding the suffix '-al'.

Initially related more to physical 'posture' or 'position' (as in stance or posture), but over time it evolved to its current primary sense of 'relating to feelings, opinions, or mental dispositions'.
