Etymology: "Underlips" is simply the plural of "underlip", the lower lip of the mouth. The singular is a plain compound of "under" and "lip", the two parts meaning just what they appear to mean. German has the same construction in "Unterlippe", and the Frisian "Unnerlippe" is a close relative, so the pattern is shared across the related Germanic languages rather than being an English invention.
