Forming the Gerund
Spanish: Edexcel IGCSE, topic 10.3.1
Forming the Gerund
The gerund is formed by adding 'ando' or 'iendo' to the stem of the verb.

AR verbs
- To form the gerund of AR verbs, take the infinitive and replace the 'ar' with 'ando'.
- Bailar → bailando.

ER/IR verbs
- To form the gerund of ER and IR verbs, take the infinitive and replace the 'er' or 'ir' with 'iendo'.
- Entender → entendiendo.
- Salir → saliendo.
Stems Ending in a Vowel
When the last letter of a verb stem is a vowel, the ER and IR gerund changes. Instead of 'iendo' it becomes 'yendo'. For example:

Ir → yendo

Oír → oyendo

Creer → creyendo

Construir → construyendo
