\Mon-\
Same as {Mono-}.

\Mon\, n. [Jap.] (Japan)
The badge of a family, esp. of a family of the ancient feudal
nobility. The most frequent form of the mon is circular, and
it commonly consists of conventionalized forms from nature,
flowers, birds, insects, the lightnings, the waves of the
sea, or of geometrical symbolic figures; color is only a
secondary character. It appears on lacquer and pottery, and
embroidered on, or woven in, fabrics. The imperial
chrysanthemum, the mon of the reigning family, is used as a
national emblem. Formerly the mon of the shoguns of the
Tokugawa family was so used.
