2. Verbs - Function
In this section we are going to focus on full/main verbs, which always act as the principal element of a verb phrase
Operator/auxiliary verbs will be studied in the Closed-class units
They can work as a whole predicator or being after operator verbs or auxiliary verbs
Predicator is the main part of a sentence, so it is recommended that we search for the verb when we do an analysis

3. Verbs - Form Verbs in English can have 5 different inflectional forms:
Vo  base form of a verb
Vs  3º person singular in present tense
Ved  simple past form
Ving  gerund form
Ven  past participle form
These forms applied for both regular and irregular verbs, although the last ones can have various forms

4. Verbs - Meaning
Verbs can express: actions, events, processes, activities, states, etc. All of these can be physical, mental, perceptual, social, among others
A good way to recognize if a verb is one, it is to change from present to past and vice versa

5. Regular vs. Irregular
One classification of verbs in English it is seen in the past simple tense, where we can see regular and irregular verbs
Regular verbs take a suffix to create the simple past form called –ed
There are specific spelling rules:
Most verbs + -ed
Verbs ending –e + d
Verbs ending consonant+y  -ied

6. Regular vs. Irregular
Irregular verbs, on the other hand, do not have one rule to follow. In general we have to memorize them in their one, two or three different forms
There is a suggestion of a classification of these verbs on AITEG, onto seven different classes according to three criteria:
Past form = participle form
All vowels identical
Inflections
However, the practicality is not clear, unless you can find (or write down) a list of these verbs grouped following this idea

7. Verb Tenses
