词根：lig (li, leag, ly) = to bind, to tie 绑
词根lig来源于拉丁语 ligare 绑 / 约束；li,leag,ly 为 lig 的变体,同义词根有来源于拉丁语的cinct,nect/nex,strain/strict/string/stress等和来源于盎格鲁-撒克逊语的bond。此外，意为to join 的junct/join/jug也与此词根含义相似。
词根lig还有二个同形异源词根一个是与来源于拉丁语 lustrare 表示“光”的lust异形同义词根lig;一个是表示“选”的意思的lig。即如果不看这个词根的来源lig有“绑”、“选”、“光”的意思，但是他们的来源完全不一样，注意区别。

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.
