noun an energetic style

originBorrowed from French verve (“animation; caprice, whim; rapture; spirit; vigour; type of expression”), probably from Late Latin verva, a variant of Latin verba (“words; discourse; expressions; language”), the plural of verbum (“word”), ultimately from Proto-Indo-European *werh₁- (“to say, speak”).
