the older place name of tayouan derives from the ethnonym of a nearby taiwanese aboriginal tribe, and was written by the dutch and portuguese variously as "taiouwang", "tayowan", etc. in his translations of dutch records, missionary william campbell used the variant "tayouan" and wrote that "taoan" and "taiwan" also occur. as dutch spelling varied greatly at the time (see history of dutch orthography), other variants may be seen. the name was also transliterated into chinese characters variously as , , , , and .
