How Well Do You Know English Slang?
1935, from Italian pizza, originally "cake, tart, pie," of uncertain origin. The 1907 "Vocabolario Etimologico della Lingua Italiana" reports it is said to be from dialectal pinza "clamp" (from Latin pinsere "to pound, stamp"). Klein suggests a connection via loan-translation with Medieval Greek pitta "cake, pie," from Greek pitta "pitch" (cf. Latin adjective piceus "of pitch"). See also pita.
