Laurel \Lau"rel\, n. [OE. lorel, laurer, lorer, OF. lorier,
laurier, F. laurier, (assumed) LL. Laurarius, fr. L. laurus.]
1. (Bot.) An evergreen shrub, of the genus Laurus (Laurus
nobilis), having aromatic leaves of a lanceolate shape,
with clusters of small, yellowish white flowers in their
axils; -- called also sweet bay.
Note: The fruit is a purple berry. It is found about the
Mediterranean, and was early used by the ancient Greeks
to crown the victor in the games of Apollo. At a later
period, academic honors were indicated by a crown of
laurel, with the fruit. The leaves and tree yield an
aromatic oil, used to flavor the bay water of commerce.
Note: The name is extended to other plants which in some
respect resemble the true laurel. See Phrases, below.
2. A crown of laurel; hence, honor; distinction; fame; --
especially in the plural; as, to win laurels.
3. An English gold coin made in 1619, and so called because
the king's head on it was crowned with laurel.
