有的啊，比如这个：就是网上最权威的词根网站了，比如输入你的这个词，结果是：abstain (v.) late 14c., "to withhold oneself," from Old French abstenir (14c.), earlier astenir (13c.) "hold (oneself) back, refrain, abstain (from), practice abstinence," from Latin abstinere"withhold, keep back, keep off," from ab(s)- "from, away from" (see ab-) + tenere "to hold" (see tenet). Specifically of liquor, late 14c. Of voting, 1796. Related: Abstained;abstaining.解释的非常详细，从哪个语言过来，进入英语的时间等。
