cranberry (n.)youdaoicibaDictYouDict
1640s, American English adaptation of Low German kraanbere, from kraan "crane" (see crane (n.)) + Middle Low German bere "berry" (see berry). Perhaps so called from a resemblance between the plants' stamens and the beaks of cranes.
Upon the Rocks and in the Moss, grew a Shrub whose fruit was very sweet, full of red juice like Currans, perhaps 'tis the same with the New England Cranberry, or Bear-Berry, (call'd so from the Bears devouring it very greedily;) with which we make Tarts. ["An Account of Several Late Voyages & Discoveries," London, 1694]
German and Dutch settlers in the New World apparently recognized the similarity between the European berries (Vaccinium oxycoccos) and the larger North American variety (V. macrocarpum) and transferred the name. In England, they were marshwort or fenberries, but the North American berries, and the name, were brought over late 17c. The native Algonquian name for the plant is represented by West Abenaki popokwa.
crane (n.)youdaoicibaDictYouDict
Old English cran "large wading bird," common Germanic (cognates: Old Saxon krano, Old High German krano, German Kranich, and, with unexplained change of consonant, Old Norse trani), from PIE *gere-no-, suffixed form of root *gere- (2) "to cry hoarsely," also the name of the crane (cognates: Greek geranos, Latin grus, Welsh garan, Lithuanian garnys "heron, stork"). Thus the name is perhaps an echo of its cry in ancient ears. Metaphoric use for "machine with a long arm" is first attested late 13c. (a sense also in equivalent words in German and Greek).

crank (n.)youdaoicibaDictYouDict
"handle for turning a revolving axis," Old English *cranc, implied in crancstæf "a weaver's instrument," crencestre "female weaver, spinster," from Proto-Germanic base *krank-, and related to crincan "to bend, yield" (see crinkle, cringe). English retains the literal sense of the ancient root, while German and Dutch krank "sick," formerly "weak, small," is from a figurative use. The 1825 supplement to Jamieson's Scottish dictionary has crank "infirm, weak, etc."

The sense of "an eccentric person," especially one who is irrationally fixated, is first recorded 1833, said to be from the crank of a barrel organ, which makes it play the same tune over and over; but more likely a back-formation from cranky (q.v.). Meaning "methamphetamine" attested by 1989.
