| a printed punctuation mark (‽), available only in some typefaces, designed to combine the question mark (?) and the exclamation point (!), indicating a mixture of query and interjection, as after a rhetorical question. |
Etymonline
Word Origin & History
niacin
"pellagra-preventing vitamin in enriched bread," 1942, coined from ni(cotinic) ac(id) + -in, chemical suffix; suggested by the merican Medical Association as a more commercially viable name than nicotinic acid.
"The new name was found to be necessary because some anti-tobacco groups warned against enriched bread because it would foster the cigarette habit." ["Cooperative Consumer," Feb. 28, 1942]
