The verbs used in the communication written or oral may be used in the singular or plural. In Portuguese there are three people for the singular and three for the plural. In this way, grammatical persons in the singular are: I, you, he or she; and in the plural they are: we, you, they or they. Therefore, grammatical people are recognized through personal pronouns.
The first person is the one who speaks or acts. Thus, when it says “I speak” or “we sing” it refers to the first person singular and the first person plural. In the second person, it refers to an individual different from you, which can be one or several people, for example, “you dance” or “you work”. In the third person the pronoun he or she is used in the singular and they or they in the plural, for example, “he has fun” and “they draw”.
Non-Personal Forms of Verbs
There are verbs that are not related to a grammatical person, these are the non-personal forms of the verb: infinitive, gerund and participle. The infinitive in Portuguese has three possible endings: -ar, -er or -ir, as in the verbs to love, to bring and to leave. The gerund incorporates the ending -ando or -iendo, like loving, bringing or leaving. The participle ends in -ado or -gone, as loved, brought or left, but it should be taken into account that there are some irregular participles such as post, seen and written. These three forms are called nonpersonal because they are not applied in front of personal pronouns. Grammatical Person
The use of the first and third person in literary texts
When writing in the first person, the narrator tells something from his personal perspective. So when I say “I saw a thief leave the establishment and I couldn’t help but stare at him in the face” I’m recounting a fact that happened to me, so I write in the first person because I’m a witness to something that happened. The narrator in the first person describes reality from the first person singular (I) or else through the first person plural (we).
When writing in the third person, the narrator becomes omniscient, that is, he knows the whole reality of a subject.
An omniscient narrator would say “a young man who came down the stairs, slipped and fell”. The third-person narrator describes something from the singular “he” or “she” and the plural “they” or “they”. Grammatical Person
It should be noted that the figure of the omniscient narrator even knows the feelings of the characters he is describing. Third-person narration can also be approached from the perspective of an objective narrator, that is, one who objectively observes what is outside the story, but does not know what the characters he describes think or feel.
