convulsively

The word convulsively is built upon the Latin verb convellere, meaning "to tear up, to pull violently, to shake." This verb itself is a composite of the intensive prefix con- (together, thoroughly) and vellere (to pull, pluck). The imagery is one of being violently wrenched or shaken apart. Over time, this literal sense of violent pulling evolved into the medical and general meaning of a sudden, involuntary, and violent muscular contraction or spasm. The adverb form convulsively thus describes an action performed in such a jerking, uncontrolled manner, or by extension, with overwhelming intensity, as if one's composure has been violently shaken.
