'institution-loving' is a compound formed from 'institution' and the adjectival combining element '-loving'. 'institution' originates from Latin, specifically the word 'institutio', where 'instituere' meant 'to set up, establish', and '-loving' traces to Old English 'lufian'/'lufu' meaning 'love'.

'institution' changed from Latin 'institutio' into Old French and then into Middle English 'institucioun', eventually becoming the modern English 'institution'. The element '-loving' developed from Old English verbal/noun forms related to 'lufu'/'lufian' and later combined with nouns to form adjectives (e.g. 'child-loving'). These parts were combined in modern English to form compound adjectives like 'institution-loving'.

Initially the elements separately meant 'established arrangement' (institution) and 'love' (loving); combined, they came to mean 'having affection for or support of institutions' — a straightforward compositional meaning that has remained stable in modern usage.
