Definition. In English grammar, the present tense is a form of the verb that is represented in English by either the third-person singular-s inflection (for example, She laughs ) or the base form (I/You/We/They laugh ). Also called the non-past. Contrast with the past tense or preterite.
Present perfect tense or passato prossimo refers to that action which has already taken place in the past but has still has its effect in the present. For example: I have eaten. Now, in Italian the passato prossimo is formed with the present indicative of essere or avere + the past participle of the main verb. Many verbs have a regular form of the past participle. Also, there are certain rules that must be kept in mind. These can be called 'Past participle agreement'.
