   - Superscripting: <code><span lang="es">1.a</span></code> _<span lang="es">1.<sup>a</sup> (primera)</span>_,
-      <code><span lang="es">v.os</span></code> _<span lang="es">V.<sup>os</sup></span>_.
+      <code><span lang="es">v.os</span></code> _<span lang="es">V.<sup>os</sup> (vistos)</span>_.
 - Slashed longhand abbreviations can be written with a horizontal line through the Orthic,
   or treated like dots: <code><span lang="es">c.u</span></code> _<span lang="es">c/u (cada unidad)</span>_
