Morphology

trefoil = tre + foil

The components correspond to 'three' + 'leaf' so the general idea 'three-lobed' is recoverable, but the forms ('tre-' and '-foil') are specialized/archaic combining forms and may not be obvious to an average B1 learner.

Etymology

The word trefoil comes from the Latin trifolium, which is made of tri- meaning 'three' and folium meaning 'leaf', so it literally means 'three-leaf' and is used for plants like clover that have three leaves.
