The most common order in affirmative sentences in Portuguese is Subject + Verb + Complement. This order shows who is performing the action, what is being done, and details such as object, place, or time. Maintaining this structure helps to keep the sentence clear.

The subject is who performs the action or about whom the sentence is. It can be explicit, when it appears in the sentence, or implicit, when it is inferred by the verb. In Portuguese, the subject can be omitted if the context is clear, especially with pronouns.

The verb expresses the action, state, or phenomenon in the sentence. In affirmative sentences, the verb agrees with the subject in number and person. The choice of verb tense indicates when the action happens.

The complement completes the meaning of the verb and can provide information such as object, place, time, or manner. In Portuguese, complements usually come after the verb in neutral order. Some verbs require a complement for the sentence to make sense.

Personal pronouns substitute nouns and avoid repetition. In the present, the pronoun can often be omitted because the verb form already indicates the person. In more formal registers, the use of the pronoun can be more frequent for clarity.

The present indicative expresses habitual actions, truths, and current situations. In affirmative sentences, we use the present with regular agreement between subject and verb. Words like today, always, and now help indicate time without changing the verb tense.

Some basic words appear frequently in affirmative sentences to indicate place, time, or object. Knowing these terms helps create complete and understandable sentences. The correct use of definite and indefinite articles also makes the sentence more natural.

Affirmative sentences end with a period. The use of a period indicates that the sentence is complete and asserts an idea. A capital letter at the start of the sentence and a period at the end are basic graphical cues of a written affirmative sentence.

The central difference is that the affirmative sentence states an action or state, while the negative uses not to negate. In Portuguese, not comes before the verb in most tenses. Maintaining the affirmative order without not creates a clear assertion.

Affirmative sentences can be short or long, depending on how much you want to inform. Adjectives, adverbs, and prepositions expand the sentence without changing its affirmative character. Clarity remains when the basic structure is maintained.
