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").
