1. 古希臘人很看不起外地人，說(shuō)外地人講話是 *barbar-，這是一個(gè)擬聲詞根，模擬小孩咿呀學(xué)語(yǔ)時(shí)口齒不清的聲音、發(fā)音，由此表示“說(shuō)話像孩子那樣口齒不清”，現(xiàn)在演化為 barbarous "未開化的"、barbarian "野蠻人，就像咱們稱呼未開化的外族人為：蠻人、夷人、胡人等"。漢語(yǔ)說(shuō)“巴拉巴拉”時(shí)，也是一種擬聲、也是一種貶義，這時(shí)英語(yǔ)用 blah-blah，這與漢語(yǔ)的擬聲完全一樣。
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- + -ous.
5. bar(棍) + bar(棍) + ian(人) => 一個(gè)人一手拿個(gè)棍子野蠻的人。
