Action that the subject does or undergoes, indicating the relationship between the subject and a possible complement. The action can be in the present, future or past tense. But the verb also expresses the 'manner' of this action because it can be a real action in this case the indicative will be used, or it can express an order and in this case there will be the imperative. In addition there is also the information of the duration and 'end' of the action which in Italian is expressed with the 'past near' or the 'future'
