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。
