• Regular Verbs: Part III

To conjugate -ar verbs, drop the ending and add:
    -o
    -as
    -a
    -amos
    -áis
    -an

To conjugate -er verbs, drop the ending and add:
    -o
    -es
    -e
    -emos
    -éis
    -en

To conjugate -ir verbs, drop the ending and add:
    -o
    -es
    -e
    -imos
    -ís
    -en

In Spanish the subject pronouns are not always required. This is because the verb endings can indicate who is performing the action.
Hablo español. (Yo is not necessary.)
I speak Spanish.

Subject pronouns are often used for clarification. For example, the verb form habla is ambiguous.
    Ud. habla
    él habla
    ella habla
