Why is the ninth month called September?
"inflammatory disease of the skin," late 14c., from Medieval Latin cingulus (loan-translation of Greek zoster "girdle"), variant of Latin cingulum "girdle," from cingere "to gird" (see cinch (n.)). The inflammation often extends around the middle of the body, like a girdle.
"thin piece of wood," c.1200, scincle, from Late Latin scindula (also the source of German Schindel), altered (by influence of Greek schidax "lath" or schindalmos "splinter") from Latin scandula "roof tile," from scindere "to cleave, split," from PIE root *sked- "to split." Meaning "small signboard" is first attested 1842. Sense of "woman's short haircut" is from 1924; the verb meaning "to cut the hair so as to give the impression of overlapping shingles" is from 1857.
"loose stones on a seashore," 1510s, probably related to Norwegian singl "small stones," or North Frisian singel "gravel," both said to be echoic of the sound of water running over pebbles.
"cover with shingles" (of houses), 1560s, from shingle (n.). Related: Shingled; shingling.
