In Spanish, many useful expressions are formed by combining two verbs. When this occurs, the first verb is conjugated, while the second verb remains in the infinitive form.

Yo voy a viajar a España.
I am going to travel to Spain.

Tú acabas de comer.
You have just eaten.

Juan puede nadar.
Juan can swim.

María vuelve a leer el libro.
María reads the book again.

--------------------------------------------------------------------------------

One such expression combines the verb volver (conjugated) with an infinitive. The preposition "a" is always used. The formula is:

volver a + infinitive = to do something again

Vuelvo a leer el libro.
I read the book again.

Cristina vuelve a conversar con mi mamá.
Christina speaks with my mom again.

Remember, volver is an o:ue stem-changing verb.

vuelvo
vuelves
vuelve

volvemos
volvéis

vuelven
