True. In Spanish, regular -ER and -IR verbs share the same endings in most forms, except for the Nosotros and Vosotros forms. For example:
-
-ER endings:
- Yo: -o
- Tú: -es
- Él/Ella/Usted: -e
- Nosotros: -emos
- Vosotros: -éis
- Ellos/Ellas/Ustedes: -en
-
-IR endings:
- Yo: -o
- Tú: -es
- Él/Ella/Usted: -e
- Nosotros: -imos
- Vosotros: -ís
- Ellos/Ellas/Ustedes: -en
As you can see, the endings for the Nosotros and Vosotros forms differ between -ER and -IR verbs.
