DID YOU KNOW?

The most famous use of "dorsal" is with "fin," whether it conjures the
ominous dorsal fin of sharks or the benign, even benevolent, image of
porpoises and dolphins. Less well-known is the botanical sense of "dorsal,"
meaning "facing away from the stem" (thus the underside of a leaf can be the
dorsal side), or the linguistic sense referring to articulations made with
the back part of the tongue (\k\ and \g\, for example). "Dorsal" can be used
of non-living things too (in particular, the backs of airplanes), as can its
opposite, "ventral," which means "relating to the belly." "Dorsal" descends
from Latin "dorsum" ("back"), which also gave us "dossier" (via French, for a
bundle of documents labeled on the back) and "reredos" ("an ornamental screen
or partition wall behind an altar").
