英语“毕业”的词根

否，graduate的词根是 ate
代表的含义是 to do, to make, to cause

grad代表了毕业，所以联系在一起就是 to make to grad

(1)."graduation" could be divided into two parts:

graduate----v
ation-----a label to tansfer verb into noun

(2).we can select "ate" out from "graduate",which verb is end with this part "ate" .It labels that meaning "make sth to do or make sth happen"

(3).No meanings about "start" or "progress" .
