Conjugation of the verb ser and estar  – Conjugación de los verbos ser y estarIn Spanish, the conjugation of the verb is the result of the root of the verb (stem) and a specific termination. For example, the conjugation of a verb for the person “Yo” (I) is different from “Ellos” (they). Thus, generally, the termination of the verb is enough to indicate which person the verb is related to, even when the person is omitted in a sentence.

  • Eres linda. (You’re beautiful.)
