Finding a four-leaf clover is a rare occurrence.
Rare → It originates from Old French *raire* (meaning uncommon or infrequent), which in turn comes from Latin *rarus* (meaning thin or sparse). The word 'rare' describes something that is uncommon or not often found.
Think of something that is 'uncommon' or 'sparse' — that's why we call it rare.
