The gerund, or present participle, is a special form of a Spanish verb which always ends in -ndo. In English it is translated as the “-ing” form of the verb (for example, “speaking”), which has lead to the frequent mistake of calling this form the “present participle”. The gerund is a verb form which has an adverbial function, not an adjectival function like a participle, nor a noun function like an infinitive.

The present participle (gerund) is formed from the infinitive of a verb by removing the (ar), (er), or (ir) ending and adding (ando) for (ar) verbs, and (iendo) for (er) and (ir) verbs.

hablar	->	hablando	speaking
caminar	->	caminando	walking
volver	->	volviendo	returning
comer	->	comiendo	eating
abrir	->	abriendo	opening
vivir	->	viviendo	living

As in English, the present participle can be used in a variety of Spanish sentences.

Yo estoy hablando con mamá.
I am talking to mom.

Ella estaba caminando bajo la lluvia.
She was walking in the rain.

Al parecer, Bryan Danielson estaría volviendo pronto a WWE.
Apparently, Bryan Danielson would soon be returning to the WWE.

Ellos estaban abriendo los regalos cuando llegamos.
