-Infinitive verbs are verbs in their most basic form. They are not used to describe the person doing the activity, but rather the activity itself.
-In English, infinitive verbs always include the word “to” before the verb. Infinitive verbs look like: to eat, to read, to sleep, to play, to speak….
-In Spanish, infinitive verbs always end in either -ar, -er, or -ir.
-Conjugated verbs are verbs that have been changed to match the person doing the action.
-They change based on who is doing the action
-In English, conjugated verbs look like: I eat, you eat, he eats, she eats, we eat, they eat
-In Spanish, normal or regular verbs change in specific ways to indicate specific people doing the action.
-To conjugate -ar verbs, first drop the -ar ending from the stem of the verb.
ex: Bailar Stem: Bail Ending: ar
-Then, add the following endings to match whoever you are talking about.
Yo -o Nosotros -amos
Tú -as Vosotros -áis
Él -a Ellos -an
