reasoning from cases

Etymology
Etymology Information

'casuistical' originates from Medieval Latin, specifically the word 'casuisticus', where Latin 'casus' meant 'case'.

Historical Evolution

'casuistical' changed from Medieval Latin 'casuisticus' and entered English via Late Latin/French forms related to 'casuistry' (Old French casuistique), eventually yielding the English adjective 'casuistical'.

Meaning Changes

Initially it referred specifically to reasoning about particular 'cases' in moral theology; over time it broadened and often came to mean 'subtle, specious, or hair-splitting reasoning' in general.
