verb (used without object)
to move with a sinuous or wavelike motion; display a smooth rising-and-falling or side-to-side alternation of movement: The flag undulates in the breeze.
Something that undulates, as a flag or rhythm, moves side to side or rises and falls like a wave. Indeed, its origin is Latin unda “wave,” via undulātus “waved, wavy,” composed of –ula, a diminutive suffix, and –ātus, a past participle suffix. Unda also yields English abound, abundant, inundate, redound, redundant, and surround. Latin unda in turn comes from the Proto-Indo-European root wed– “water, wet,” ultimate source of the names of two substances that may cause some to undulate, as it were, on their feet: vodka (via Russian) and whiskey (Irish or Scots Gaelic). Best to stay hydrated, another derivative of wed-, via Greek hýdōr “water.” Undulate entered English in the 1600s.

Hangdog is a compound of hang and dog, originally an expression for a person deemed so low and despicable they were considered fit only to hang a bad dog or be hanged like one, as was once the custom; hence, by extension, “browbeaten, defeated, intimidated abject.” In the American South the adjectival form doghanged also occurs, like Southern peckerwood for woodpecker. Hangdog entered English in the second half of the 17th century.
