Morphology

trefoil = tre + foil

The ornamental sense is related to the idea 'three-leaved' which is derivable from the parts, but the combining forms and the architectural usage are specialized and may not be transparent to learners.

Etymology

The word trefoil also names a decorative shape of three round 'leaves' joined in a circle; it comes from Latin trifolium, from tri- meaning 'three' and folium meaning 'leaf', and this three-part design was often used in church art to suggest the Trinity.
