Transitive verbs
Transitive verbs are verbs that can take a direct object. Transitive construction verbs take a preposition ‘a’ when the immediate purpose is something personalized or a specific person. In most cases, these objects replace direct object pronouns ‘ los’, ‘lo’, or ‘las’. For example;
Veo una casa. La veo. (I see a house. I see it)
Veo a tu Hermana. La Veo (I see your sister. I see her.)
Gerunds are present adverbial participles. In English, they are the kind of verbs ending with “-ing.” But in Spanish gerunds end in –endo or –ando. They can make progressive verb forms by combining with types of setar, for example; Estoy viendo la luz. ( I am seeing the light.) Spanish gerunds are different from other gerunds in different ways; for example, they can function as adverbs. For instance, viendo can be used to describe how activity occurred in, for example, “corre viendo todo” (I run while seeing everything.)
Auxiliary verbs or helping verbs in Spanish are used in conjunction with others with another verb to project a relevant meaning, like a tense. Haber (to have) is an example of auxiliary verbs that can be used in conjunction with a past participle to form a perfect tense. For example, “He comido” (I have eaten), in this example, he has been used to create perfect tense. Estar is another common auxiliary verb, as on “estoy comiedo” I am eating.
