Word History

Etymology

borrowed from Middle French, going back to Old French, borrowed from Latin vehement-, vehemens, vēmens "violent, vigorous, (of feelings) overmastering, powerful," perhaps from vehere "to convey, carry along, drive" + -mens, adjective suffix (as in clēmens "mild, calm") of uncertain origin

Note: Alternatively explained as a prefix vē- "faulty, excessive or deficient" and ment-, mens "mind," in which case -ehe- is an unetymological spelling of the long vowel. Though this would account for vehemens in place of *vehimens (with normal vowel weakening), the word never has the sense "mentally deranged" (the meanings of the presumed parallel formations vēcors and vēsānus).

First Known Use

15th century, in the meaning defined above
