The Accent Mark Rule
Notice that the 'i' gets an accent mark (varío, varía) in many present tense forms. This is to make sure you pronounce the 'i' clearly instead of blending it into the next vowel.
Using 'de' with Variar
When you want to say you are changing something specific, like your opinion or your route, you often use the word 'de' after the verb: 'variar de opinión'.
Missing the Accent
Mistake: “Yo vario el plan.”
Correction: Yo varío el plan. Without the accent on the 'i', the pronunciation changes completely.
Variar vs. Cambiar
Mistake: “Quiero variar mis dólares por pesos.”
Correction: Quiero cambiar mis dólares por pesos. Use 'cambiar' for exchanging things; use 'variar' for making something different or diverse.
