Etymology

The word for the marsh is inherited from Middle English fen, also feon and ven,[2] inherited from Old English fenn (“mud, dirt; fen, marsh”),[3][4][5][6][7] from Proto-Germanic *fanją (“swamp, marsh”).[1][5][8][9] Its Germanic cognates include Old Frisian fenne, Old Saxon feni, Middle Dutch venne, Dutch veen, Old High German fenna, German Fenn, Old Norse fen (“quagmire”) and Gothic 𐍆𐌰𐌽𐌹 (fani, “clay, mud”).[10][9][5][8] Beyond Germanic, it goes back to Proto-Indo-European *pen- (“swamp”),[5][9][11] with Old Prussian pannean (“marsh”), Sanskrit पङ्क (páṅka, “mud, bog”), Gaulish anam (“water”) and Middle Irish enach (“swamp”).[5][9][12][1][8][13] Kroonen reconstructs *pon-io- and considers it potentially a collective noun identical to the Old Prussian word.[8] Etymonline and Weekley consider Italian fango, Spanish fango, Old French fanc and French fange (“mud”) to be loans from Germanic.[5][14]

Earliest recorded meaning

Barnhart dates the Old English word to about 725, in Beowulf, for a marsh or for mud.[9] The OED's first records are in Ælfred's translations: low land under water in that of Boethius, and mud, mire in that of Gregory's Pastoral Care.[10] The English Fens appear in the Anglo-Saxon Chronicle under the year 905.[10][4]

Semantic evolution

Weekley and Partridge took "mud" to be the original sense,[14][15] which is the Gothic meaning.[8][9] In English the sense "mud, mire, filth, excrement" lasted until 1600,[10] while the marsh sense has lasted from Old English to the present.[10] Middle English had pairs such as feld and fen and fen and flod.[2] The Middle English Dictionary notes that the "dung" sense overlaps with a word from French.[2] Mapping Metaphor links words for marshland with bodily excretion from the first half of the 14th century.[16] Johnson (1755) defined it as "a marsh; low flat and moist ground; a moor; a bog", and quoted Shakespeare's "lonely dragon, that his fen makes fear'd" from Coriolanus.[17] In ecology it is specifically wet land with alkaline, peaty soil.[18][19] In Wexford, Devon and Cornwall it took the form ven.[20] In underworld slang from the turn of the 18th century it was a prostitute or bawd, an image of dirtiness.[21]

Borrowing
First attested

Borrowed from
Chinese 分

Etymology

The word for the coin is borrowed from Chinese 分 (fēn, “a hundredth part”).[10][18][23][24][1][19]

Earliest recorded meaning

A Chinese monetary unit: 1852, in C. B. Hillier in the Transactions of the China Branch of the Royal Asiatic Society,[10][6] The OED notes that it was formerly a candareen.[10]

Semantic evolution

Merriam-Webster Unabridged notes that before the establishment of the People's Republic in 1949 the unit was also known as the cent.[6] Its value is one hundredth of a yuan and one tenth of a jiao.[10][6][18]

Timeline

  • 1852 – a Chinese monetary unit, formerly the same as a candareen.[10][6] Dictionary.com dates it to 1905–10,[25] and the Merriam-Webster Collegiate to 1916.[19]

Meanings

Noun

  1. A monetary unit of China equal to one hundredth of a yuan, or a coin of this value.[10][6][18]
  2. Formerly, a candareen.[10][6]
  • vinny

Usage notes

The coin is pronounced /fʌn/ in British and /fən/ in American English, unlike the marsh.[10][6] A dialect word for mould, especially a disease of hops, is recorded from Old English on, and is probably an ablaut variant of the Germanic base of the marsh word, compare vinny.[10][18][20] The boys' exclamation fen! used to forbid a move at marbles, recorded from 1823, is usually taken to be a corruption of fend.[10][6][20] A fen was also a section of Avicenna's Canon, a Medieval Latin term from an Arabic word for a species or class, used by Chaucer in the Pardoner's Tale.[10][2]
