词根:ali, al, alter(ulter, altru) = other 其他的, 变更

  词源:al,alter都来源于拉丁语的alter 意思是“其他的”,ulter,altru是词根alter的变形。词根ali的意思也是“其他的”。《赢在单词》这本词源书解释ali与al(ter)不是同源,ali来源于拉丁语的alius;al(ter)和ali是异源异形同义词根,由于本站词根是按词义介绍的,所以把它们放在一起了,而刘毅的英文字根字典把ali,al(ter)列为同源异形根,都来源于alter(=other)。all也是它们的同义词根,all来源于希腊词根词根allos ,也表示“其它的”意思,其中,由 -ali- 所构成的单词大部分会发生转意,还需要我们在使用时仔细辨认。但词根 -alter- 在单词中的意思却非常明显。

  这里的词根al与另一个来源于拉丁语alere(to nourish) 的词根al,是同形异源词根,注意不要混淆。

词根词缀:phront-, phorntid-; phronemo-, phron-

【来源及含义】Greek: thought, care, attention; think, thinking, contemplation

【相关描述】The Greeks had a word, phrontisterion, to indicate a place for thought and study or a "thinking-shop" (think tank?). Aristophanes (c. 450-c. 380 B.C.), was an Athenian dramatist who is known to have written more than 40 comedies that gave satiric expression to his strong, conservative prejudices against certain trends and personalities in the Athens of his day. It was this Aristophanes who used the Greek equivalent of phrontistery to ridicule the school of Socrates.

The Greek noun was derived from phrontistes (philosopher, profound thinker, one with intellectual pretensions) from the verb phrontizein (to reflect), based on phrontis (thought, reflection). The word phrontist applies to a "deep thinker," a "person involved in study, reflection, meditation," and it, too, in its Greek form, was applied ironically by Aristophanes to Socrates himself.
