Collier's New Encyclopedia (1921)/Fillet
FILLET, in ordinary language, a band
of metal, linen, or ribbon worn round the
head. Also the fleshy part of the thigh;
applied most commonly to veal. Also
portions of meat or fish removed from
the bone and served either flat or rolled
together and tied round; the term is
specially applied to the under-cut of the
sirloin of beef, served whole or cut into
steaks, and to slices of flat-fish removed
from the bone. In anatomy, a collection
of fibers passing upward from the
anterior columns of the spinal cord. Also
a similar bundle of fibers in the corpus
callosum.

In architecture, a small flat face or
band used principally between moldings
to separate them from each other in
classical architecture; in the Gothic,
Early English, or decorated styles of
architecture, it is also used on larger
moldings and shafts.
