Etymology
Etymology Information

'anti-rationalism' originates from modern English, specifically from the prefix 'anti-' (from Greek 'anti' meaning 'against') combined with 'rationalism' (from Latin 'ratio' meaning 'reason' plus the suffix '-ism').

Historical Evolution

'rationalism' changed from early modern philosophical Latin and French usage (for example French 'rationnalisme') derived from Latin 'ratio' and eventually became the modern English word 'rationalism'; putting 'anti-' before it formed the compound 'anti-rationalism' in modern English.

Meaning Changes

Initially, the term was used chiefly to indicate opposition to the specific philosophical doctrine called 'rationalism'; over time it has broadened to refer to any opposition or distrust of reason or reason-based methods in various social, cultural, or political contexts.
