Etymology
Etymology Information

'trefoil' originates from Latin, specifically the word 'trifolium', where 'tri-' meant 'three' and 'folium' meant 'leaf'.

Historical Evolution

'trifolium' changed into Old French forms (e.g. 'trefle') and Middle English 'trefoile', and eventually became the modern English word 'trefoil'.

Meaning Changes

Initially, it meant 'three-leaved (plant)' in Latin, and over time it also came to refer to the three-lobed decorative form; both senses survive in modern usage.
