cuspidor
noun
cus·pi·dor ˈkə-spə-ˌdȯr 
: spittoon
Did you know?
Cuspidor entered English in the early 18th century via the Portuguese word cuspidouro, meaning "place for spitting." The Portuguese word, unsurprisingly, has its origins in Latin: the word conspuere comes from the prefix com- and spuere, meaning "to spit." ("Spuere" is also the source of "spew" and sputum.) Since the early 19th century, "cuspidor" has been competing with (and losing to) "spittoon," but "cuspidor" beats "spittoon" in one particular category: the receptacle for spit at a dentist's office is more often referred to by the older word.
