请教一个英语单词determine 的词根词缀,麻烦解释一下

中文简解:
v. 决定,决心要
[计算机] 确定

单词结构:de[r5] + termin[r1] + e[r1]
构词法则:de:使成…、作成…、或仅作加强意义 + termin:界限 + e:词尾 → 到了最后的界面 → 必须做出“决定”
详解例句:
We determined to go to the railway station at once./r/n 我们决定立刻去火车站./r/n
The court determined that the man was guilty of assault./r/n 法庭裁定那个人犯了侵犯人身罪./r/n
