Why is the ninth month called September?
1540s, from Latin lotus, from Greek lotos, name used for several plants before it came to mean Egyptian white lotus (a sense attested in English from 1580s); perhaps from a Semitic source (cf. Hebrew lot "myrrh"). The yogic sense is attested from 1848. Lotus-eaters (1812) are from Greek lotophagoi, mentioned in "Odyssey," book IX.
