In Spanish grammar, the gerund is a non-finite verbal form used to express an action that is happening at the same time as the main verb of a sentence. Gerunds are formed by adding the suffix “-ando” to the stem of “-ar” verbs and “-iendo” to the stem of “-er” and “-ir” verbs. The gerund is similar to the English “-ing” form of a verb, and it can be used in various contexts, such as with verbs of motion, perception, and progressive tenses.
