In the Preterit Tense of Spanish, verbs change depending on the subject pronoun. The changes can involve shifts in the stem of the verb. For example, in the verb "competir" (to compete) for "he," the stem change from "e" to "i" occurs resulting in "compitió." Similarly, "Ser" (to be) conjugated for "vosotros" becomes "fuisteis."
Understanding these stem changes and conjugations is crucial for correctly forming verbs in the Preterit Tense in Spanish. Each verb follows a pattern based on its infinitive form and the subject pronoun it's paired with. This exercise helps reinforce these conjugation patterns for different verbs in the Preterit Tense.
