Hypercatalectic

A hypercatalectic line is a line of metered verse that includes at least one extra syllable at the end. Intentionally writing hypercatalectic line or lines is called hypercatalexis.

Lines written in Iambic pentameter, or other iambic verse, that contain feminine rhymes are usually hypercatalectic, as these lines from Shakespeare:

A woman’s face with nature’s own hand painted,

Hast thou, the master mistress of my passion;

A woman’s gentle heart, but not acquainted

With shifting change, as is false women’s fashion...

But since she prick’d thee out for women’s pleasure,

Mine be thy love and thy love’s use their treasure.

(Sonnet XX)
