Verbs are words that indicate actions, existence (being / being), possession (having) or mood.
In English, we use the preposition "a" to form the infinitive, for example: "speak", (speak), "eat" (eat), "change" (change), etc.
Verbs are the most complicated part of the sentence. There are many types of verbs. The verb can indicate the main action (the main verb). An auxiliary verb add to the action or help the main verb (also called "complementary verbs"). Modal verbs add modality (possibility, capacity, permission, prohibition, obligation, etc.). Transitive verbs connect a subject with an object. Other verbs only need a subject (intransitive verbs). There are verbs that are composed of more than one word (prepositional verbs and phrasal verbs). Verbs can be active or passive. For now and at this level, we focus on the uses of the main and auxiliary verbs.
In addition to the many types and uses of verbs, we need to conjugate verbs. The conjugation of verbs depends on the subject and time. In the following lessons and levels, there are explanations for the conjugations of time. At this level, we are only going to study the present tenses, the simple and the present continuous of the verbs.
