'frequently-exhibited' originates from Modern English, specifically formed from the adverb 'frequently' and the past participle 'exhibited'. 'Frequently' ultimately comes from Latin 'frequens' (via Old French 'frequent'), where the root 'frequ-' conveyed the idea of being 'numerous' or 'repeated'. 'Exhibited' derives from Latin 'exhibere', where 'ex-' meant 'out' and 'habere' meant 'to hold or have'.

The component 'frequently' developed from Latin 'frequens' into Old French 'frequent' and then into Middle English as 'frequent' with the adverbial form 'frequently'. 'Exhibit' came from Latin 'exhibere' into Old French and Middle English as 'exhibiten'/'exhibite', later regularized to modern English 'exhibit' and its past participle 'exhibited'. The compound adjective form 'frequently-exhibited' is a modern English formation combining the adverb + past participle.

Initially, the separate elements meant 'repeated/often' (frequently) and 'to hold forth/show' (exhibit). Over time, combined as 'frequently-exhibited' the phrase came to mean simply 'shown often' or 'displayed on many occasions' in contemporary usage.
