honeysuckle n.

Middle English hony, from Old English hunig "honey," from Proto-Germanic *hunang- (source also of Old Norse hunang, Swedish honung, Old Saxon honeg, Old Frisian hunig, Middle Dutch honich, Dutch honig, Old High German honang, German Honig "honey"), of uncertain origin. Perhaps from a PIE *k(e)neko- denoting yellow, golden, or brownish colors (compare Sanskrit kancan- "golden," Welsh canecon "gold," Greek knēkos "yellowish"), or perhaps from a substratum word. Finnish hunaja is a Germanic loan-word.

The more common Indo-European word is represented in Germanic by the Gothic word for "honey," miliþ (from PIE root *melit- "honey"). A term of endearment from at least mid-14c.; extended form honey-bunch attested by 1904. Meaning "anything good of its kind" is 1888, American English. Honey-locust, North American tree, so called from 1743, said to be named from a sweet pulp made by Native Americans from the tree's beans.

Old English sucan "to suck," from a Proto-Germanic word of imitative origin (cognates: Old Saxon, Old High German sugan, Old Norse suga, Danish suge, Swedish suga, Middle Dutch sughen, Dutch zuigen, German saugen "to suck"), possibly from the same source as Latin sugere "to suck," succus "juice, sap;" Old Irish sugim, Welsh sugno "to suck;" see sup (v.2). As a noun from c. 1300.

Meaning "do fellatio" is first recorded 1928. Slang sense of "be contemptible" first attested 1971 (the underlying notion is of fellatio). Related: Sucked; sucking. Suck eggs is from 1906. Suck hind tit "be inferior" is American English slang first recorded 1940.

The old, old saying that the runt pig always sucks the hind teat is not so far wrong, as it quite approximates the condition that exists. [The Chester White Journal, April 1921]
