In some verbs, stressed o changes to ue in present-tense forms.
The idea
Use changed forms such as puedo, puedes, vuelve and duermen. Nosotros and vosotros keep o: podemos and podéis.
Examples
- Yo puedo esperar aquí.I can wait here.
- ¿Puedes abrir la puerta?Can you open the door?
- Podemos caminar hasta allí.We can walk there.
- El tren vuelve a las seis.The train returns at six.
- Los niños duermen temprano.The children sleep early.
- ¿Vuelves mañana?Are you coming back tomorrow?

Watch out
