duck: [OE] A duck is a bird that ‘ducks’ – as simple as that. It gets its name from its habit of diving down under the surface of the water. There is no actual record of an English verb duck until the 14th century, but it is generally assumed that an Old English verb *dūcan did exist, which would have formed the basis of the noun duck. It came from a prehistoric West Germanic verb *dukjan, which also produced German tauchen ‘dive’.

English is the only language which uses this word for the bird, although Swedish has the term dykand, literally ‘dive-duck’, which refers to the ‘diver’, a sort of large waterbird. Nor is it the original English word: the Anglo-Saxons mainly called the duck ened, a term which survived until the 15th century. This represents the main Indo-European name for the duck, which comes from an original *anə ti- and is found in Greek nessa, Latin anas, German ente, Dutch eend, Swedish and, and Russian utka.

[duck etymology, duck origin, 英语词源]
charlatan (n.)youdaoicibaDictYouDict
1610s, from French charlatan "mountebank, babbler" (16c.), from Italian ciarlatano "a quack," from ciarlare "to prate, babble," from ciarla "chat, prattle," perhaps imitative of ducks' quacking. Related: Charlatanism; charlatanical; charlatanry.
duck (n.1)youdaoicibaDictYouDict
waterfowl, Old English duce (found only in genitive ducan) "a duck," literally "a ducker," presumed to be from Old English *ducan "to duck, dive" (see duck (v.)). Replaced Old English ened as the name for the bird, this being from PIE *aneti-, the root of the "duck" noun in most Indo-European languages.
In the domestic state the females greatly exceed in number, hence duck serves at once as the name of the female and of the race, drake being a specific term of sex. [OED]
As a term of endearment, attested from 1580s. duck-walk is 1930s; duck soup "anything easily done" is by 1899. Duck's ass haircut is from 1951. Ducks-and-drakes, skipping flat stones on water, is from 1580s; the figurative sense of "throwing something away recklessly" is c. 1600.
fowl (n.)youdaoicibaDictYouDict
Old English fugel "bird, feathered vertebrate," from Proto-Germanic *fuglaz, the general Germanic word for "bird" (cognates: Old Saxon fugal, Old Frisian fugel, Old Norse fugl, Middle Dutch voghel, Dutch vogel, German vogel, Gothic fugls "a fowl, a bird"), perhaps a dissimilated form meaning literally "flyer," from PIE *pleuk- (see fly (v.1)).

Displaced in its original sense by bird (n.); narrower sense of "barnyard hen or rooster" (the main modern meaning) is first recorded 1570s; in U.S. this was extended to domestic ducks and geese.
goose (n.)youdaoicibaDictYouDict
"a large waterfowl proverbially noted, I know not why, for foolishness" [Johnson], Old English gos "a goose," from Proto-Germanic *gans- "goose" (cognates: Old Frisian gos, Old Norse gas, Old High German gans, German Gans "goose"), from PIE *ghans- (cognates: Sanskrit hamsah (masc.), hansi (fem.), "goose, swan;" Greek khen; Latin anser; Polish gęś "goose;" Lithuanian zasis "goose;" Old Irish geiss "swan"), probably imitative of its honking.
Geese are technically distinguished from swans and from ducks by the combination of feathered lores, reticulate tarsi, stout bill high at the base, and simple hind toe. [Century Dictionary]
Spanish ganso "goose" is from a Germanic source. Loss of "n" sound is normal before "s." Plural form geese is an example of i-mutation. Meaning "simpleton, silly or foolish person" is from early 15c. To cook one's goose first attested 1845, of unknown origin; attempts to connect it to Swedish history and Greek fables are unconvincing. Goose-egg "zero" first attested 1866 in baseball slang, from being large and round. The goose that lays golden eggs (15c.) is from Aesop.
-s (1)youdaoicibaDictYouDict
suffix forming almost all Modern English plural nouns, gradually extended in Middle English from Old English -as, the nominative plural and accusative plural ending of certain "strong" masculine nouns (such as dæg "day," nominative/accusative plural dagas "days"). The commonest Germanic declension, traceable back to the original PIE inflection system, it is also the source of the Dutch -s plurals and (by rhotacism) Scandinavian -r plurals (such as Swedish dagar).

Much more uniform today than originally; Old English also had a numerous category of "weak" nouns that formed their plurals in -an, and other strong nouns that formed plurals with -u. Quirk and Wrenn, in their Old English grammar, estimate that 45 percent of the nouns a student will encounter will be masculine, nearly four-fifths of them with genitive singular -es and nominative/accusative plural in -as. Less than half, but still the largest chunk.

The triumphs of -'s possessives and -s plurals represent common patterns in language: using only a handful of suffixes to do many jobs (such as -ing), and the most common variant squeezing out the competition. To further muddy the waters, it's been extended in slang since 1936 to singulars (such as ducks, sweets, babes) as an affectionate or diminutive suffix.

Old English single-syllable collectives (sheep, folk) as well as weights, measures, and units of time did not use -s. The use of it in these cases began in Middle English, but the older custom is preserved in many traditional dialects (ten pound of butter; more than seven year ago; etc.).
web (n.)youdaoicibaDictYouDict
Old English webb "woven fabric, woven work, tapestry," from Proto-Germanic *wabjam "fabric, web" (cognates: Old Saxon webbi, Old Norse vefr, Dutch webbe, Old High German weppi, German gewebe "web"), from PIE *webh- "to weave" (see weave (v.)).

Meaning "spider's web" is first recorded early 13c. Applied to the membranes between the toes of ducks and other aquatic birds from 1570s. Internet sense is from 1992, shortened from World Wide Web (1990). Web browser, web page both also attested 1990.
