A lover, often secret, not allowed by law or custom.

He was her paramour for many years before she finally divorces her husband.
Commentary
Paramour includes the prefix par-, "by or through." This implies a relationship based solely on love, often physical love, rather than on a social custom or ceremony. Today, it usually refers to the lover of a married man or woman.
