Le"o*nine (lē"&osl;*nīn), a. [L. leoninus, fr. leo, leonis, lion: cf. F. léonin. See Lion.] Pertaining to, or characteristic of, the lion; as, a leonine look; leonine rapacity. -- Le"o*nine*ly, adv.

Leonine verse, a kind of verse, in which the end of the line rhymes with the middle; -- so named from Leo, or Leoninus, a Benedictine and canon of Paris in the twelfth century, who wrote largely in this measure, though he was not the inventor. The following line is an example:

Gloria factorum temere conceditur horum.

LEONINE, adj. Unlike a menagerie lion. Leonine verses are those in
which a word in the middle of a line rhymes with a word at the end, as
in this famous passage from Bella Peeler Silcox:

The electric light invades the dunnest deep of Hades.
Cries Pluto, 'twixt his snores: "O tempora! O mores!"

It should be explained that Mrs. Silcox does not undertake to
teach pronunciation of the Greek and Latin tongues. Leonine verses
are so called in honor of a poet named Leo, whom prosodists appear to
find a pleasure in believing to have been the first to discover that a
rhyming couplet could be run into a single line.
