(B) The etymology of English noun canyon is directly descended, in 1834, from American/Mexican Spanish noun masculine cañón (meaning "canyon"). Beyond that, it is uncertain--Webster online said "probably from obsolete Spanish calle "street" from Latin callis footpath, whereas Online Etymology Dictionary states the source was Latin canna but concedes "early spelling callon (1560s) might suggest a source in (Latin) calle "street."
(C) The Latin noun feminine canna--descending from Ancient Greek kanna "reed"--means "reed, cane."
