Meaning and background
The story behind Guillermo
Guillermo is the Spanish form of William, with a reference pronunciation that differs substantially from an English reading of the letters. The initial gui and doubled l are worth hearing in context before settling on an improvised respelling. For a dog, its longer form may be the attraction if you enjoy a full personal name. A nickname is optional, not required to make it usable. If Guillermo honours a particular person, their pronunciation and exact spelling should lead the choice.
