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).
