1. 古希腊人很看不起外地人，说外地人讲话是 *barbar-，这是一个拟声词根，模拟小孩咿呀学语时口齿不清的声音、发音，由此表示“说话像孩子那样口齿不清”，现在演化为 barbarous "未开化的"、barbarian "野蛮人，就像咱们称呼未开化的外族人为：蛮人、夷人、胡人等"。汉语说“巴拉巴拉”时，也是一种拟声、也是一种贬义，这时英语用 blah-blah，这与汉语的拟声完全一样。
2. from PIE root *barbar- echoic of unintelligible speech of foreigners.
3. Originally not entirely pejorative, its sense darkened after the Persian wars. The Romans (technically themselves barbaroi) took up the word and applied it to tribes or nations which had no Greek or Roman accomplishments.
4. barbar- + -ic.
