fiddler

The word 'fiddle' for the violin entered English around 1200 from Old High German 'fidula', which is likely related to the early Medieval Latin 'vitula', a stringed instrument. This Latin term may derive from 'Vitula', the Roman goddess of joy and victory, or from the Indo-European root wet-, meaning "to weave" or "to string", conceptually linking to the instrument's strings. The agent noun 'fiddler' (one who fiddles) was formed in English by adding the native Germanic suffix '-er', creating a term that first denoted a violin player and later, by the 17th century, acquired the figurative sense of someone who tinkers or deals with matters dishonestly.

The word 'fiddler' is a simplex noun derived from the verb 'fiddle' (to play the fiddle, or to tinker) combined with the agent noun suffix '-er'. The base 'fiddle' is a loanword whose form is not productively segmented into smaller meaningful units in modern English.
