AR verbs with spelling changes There are various ways in Spanish to express an action in the past. This exercise treats the simple past, or PRETERIT, which means that a verb is a one-word verb, already completed, which took place only once. For example, "I speak" is the present tense. "I spoke" is the past tense. Formation: To conjugate regular AR verbs in the past drop the AR from the infinitive and you are left with HABL. Add the following endings to the stem: é, aste, ó, amos, astéis, and aron. For example, HABLAR in the preterit conjugates as follows: Hablé-I spoke Hablaste-You spoke Habló-He,she, you (formal) spoke Hablamos-We spoke Hablastéis-You all spoke Hablaron-They spoke However, there are a few verbs that have adaptations in the YO for pronunciation reasons, specifically AR verbs which end in CAR, ZAR or GAR. CAR verbs such as BUSCAR have a QUE in the yo: Busqué= I searched. GAR verbs such as LLEGAR have a GUE in the yo: Llegué=I arrived. ZAR verbs such as ALMORZAR have a CE in the yo: Almorcé= I ate lunch. Other than this spelling change in the YO, the verbs is treated like all regular AR verbs. Typical verbs of these types are: Almorzar, Comenzar, Empezar, abrazar, alcanzar Jugar, llegar, pagar Buscar, tocar, sacar, pescar In the exercise that follows, conjugate the AR verbs in the past tense for the subjects provided.
