'tassel' originates from Old French, specifically the word 'tasel' (or 'tassel'), where the element likely referred to a 'small tuft' or 'bundle'.

'tassel' changed from Old French 'tasel' (used in medieval times) into Middle English as 'tasel' or 'tassel' and eventually became the modern English word 'tassel'.

Initially, it meant 'a small tuft or bunch' and over time it has retained that basic sense while being applied to various decorative contexts (clothing, furnishings, academic wear).
