köken: Either from an onomatopoeic root or from Lombardic (s)pizza, from Proto-Germanic *spitjaz, related to *spitō (“spike”), whence German Spitze (“peak”).
köken: The first element is certainly a Sino-Vietnamese word from 保 (“to protect”). Some sources suggest that this word is from 保家 (through a Southern Min lect), but this might just be a case of folk etymology. The Southern Min word might have given rise also to Thai โปเก (“shoddy; of inferior quality”)
