Spelling Change for ZAR verbs

Confusing 'Utilizar' and 'Usar'
Mistake: “Using 'utilizar' in very casual, everyday conversation, such as 'Voy a utilizar el baño.'”
Correction: While not strictly wrong, 'usar' is much more common and natural for simple, everyday objects or actions. 'Voy a usar el baño.' Use 'utilizar' when talking about resources, strategies, or in writing.
