Regnal number

The Aztecs did not use regnal numbers; they were given retroactively by historians to more easily distinguish him from the first Moctezuma, referred to as Moctezuma I. The Aztec chronicles called him Motecuhzoma Xocoyotzin, while the first was called Motecuhzoma Ilhuicamina or Huehuemotecuhzoma ('Old Moctezuma'). Xocoyotzin (IPA:) means 'honored young one' (from xocoyotl 'younger son' + suffix -tzin added to nouns or personal names when speaking about them with deference).
