Etymology
The word 'trefoil' is a direct borrowing from Anglo-French, itself derived from the Latin phrase trifolium, meaning "three-leaved plant". The Latin components are tri- (three) and folium (leaf). The term entered English in the medieval period, initially describing clover and similar plants. Its application later expanded to architecture and heraldry, where the three-lobed shape became a common decorative and symbolic motif, logically extending the literal botanical meaning into an abstract design element.

Structure: tre (three) + foil (leaf)
