In this Spanish lesson led by Daniela, students learn how to express feeling unwell using the verb “doler,” which means “to hurt” or “to be painful.” The lesson covers the specific structure of using “doler” with body parts, such as “me duele la cabeza” for “I have a headache,” and the variations of the verb’s usage depending on the subject pronoun, like “yo,” “tú,” “él/ella,” “nosotros,” “vosotros,” and “ellos/ellas,” including adding an “n” for plural body parts. This lesson is part of Unit 5, “Vivir Saludable” (Healthy Living).
