There can be up to five different forms of verbs, usually referred to as V1, V2, V3, V4 and V5. Verbs are simply words that express action or a certain state of being.
The –s form is used as the third-person singular. The verb is formed by adding –s (or sometimes –es) to the end of the base form of the verb. This rule applies to both, regular and irregular verbs, i.e. the –s form of the verb is always created the same way.
