Verbal (V)
A Verbal component is the chanting of esoteric words that sound like nonsense to the uninitiated. The words must be uttered in a normal speaking voice. The words themselves aren't the source of the spell's power; rather, the particular combination of sounds, with specific pitch and resonance, sets the threads of magic in motion. Thus, a creature who is gagged or in an area of magical silence can't cast a spell with a Verbal component.
Creating Verbal Components
If you'd like to say a spell's Verbal component, you may make up the words. However you make them, the goal is to create something that's easy to say and that doesn't mean anything in the real world. Consider this method: take the name of the spell, keep only one instance of each of its letters, and rearrange the remaining letters into words. For example, remove the second l from Fireball and rearrange the remaining letters to create Ber Fila or Fel Bira.
