verve
Verve (noun) means Great energy and enthusiasm, especially the kind that brings a piece of art, music or writing to life.
Etymology
Borrowed 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"). It is a doublet of verb and word.
