BanditNationShouldn't shouts all have 3 1-syllable Rotmulaag, Words of Power? Most shouts in this thread have at least 1 2-syllable Word. In Skyrim, i've only ever heard 1-syllable Rotmulaag.
You're correct, ideally a Shout should follow that format. There is one instance in the Dragonborn DLC where Miraak uses a four-word Shout of sorts ("Ziil los dii du", "your soul is mine to devour"). This really shouldn't be thought of as a Dragon Shout though since it's not made up of Words of Power, but is an actual sentence.
