sandbank的词源

英文词源

crocodile: crocodile: [13] The crocodile gets its name from its habit of basking in the sun on sandbanks or on the shores of rivers. The word means literally ‘pebble-worm’, and it was coined in Greek from the nouns krókē ‘pebbles’ and drilos ‘worm’. The resulting Greek compound *krokódrīlos has never actually been found, for it lost its second r, giving krokódīlos, and this r reappeared and disappeared capriciously during the word’s journey through Latin and Old French to English. Middle English had it – the 13th century form was cokodrille – but in the 16th century the modern r-less form took over, based on Latin crocodīlus.
bank (n.2): "earthen incline, edge of a river," c. 1200, probably in Old English but not attested in surviving documents, from a Scandinavian source such as Old Norse banki, Old Danish banke "sandbank," from Proto-Germanic *bangkon "slope," cognate with *bankiz "shelf" (see bench (n.)).
shelf (n.2): "sandbank," 1540s, of unknown origin. Related: Shelfy "abounding in sandbanks."
