Stem Change: O to UE
The verb volar (to fly) is irregular. In the present tense, the 'o' changes to 'ue' in most forms, except for 'nosotros' and 'vosotros'. This is why we say vuela instead of vola.
Dual Function of 'Vuela'
'Vuela' is used for two important things: 1) To state what 'he, she, or it' does (present indicative). 2) To give an informal command to a friend ('tú' imperative).
Forgetting the Stem Change
Mistake: “El pájaro vola.”
Correction: The correct form is *El pájaro vuela*. Always remember the 'o' changes to 'ue' when stressed.
