In Spanish, there are 3 types of verbs—the root,+ AR, ER, or IR (for “hablar” the root is HABL + AR). This makes up the infinitive or base verb, which you later change to indicate who is doing the action and when.

AR
hablar to speak
bailar to dance
formar to form
cantar to sing

ER
ver to see
correr to run
leer to read
beber to drink

IR
vivir to live
asistir to attend
insistir to insist
escribir to write
