Agirás

Agirás is the second-person singular future indicative form of the Portuguese verb agir, meaning "you will act." It denotes a future action by the subject you (tu), and is common in contexts and dialects where the informal second person is used, particularly in European Portuguese and some regional varieties. In Brazilian Portuguese, the corresponding informal form is less frequent, as tu is less dominant and você is commonly used instead.

Etymology and classification: Agir derives from Latin agere and is a regular -ir verb in Portuguese, with future indicative forms built on the infinitive agir plus the standard -ás ending for tu. The form agirás shares the same regular pattern as other -ir verbs in the future tense, such as agirás, agirá, agiremos, agireis, and agirão.

Conjugation overview (indicative, future): eu agirei, tu agirás, ele/ela agirá, nós agiremos, vós agireis, eles/elas agirão. While the tu form is the focal point of this entry, the full paradigm follows the typical -ir verb future conjugation.

Usage notes: agirás appears in formal or literary writing, speeches, or dialogue where tú is used. It can express intent, promises, or predictions about the subject’s future behavior. It is often found alongside conditionals or relative clauses, as in sentences like “Se fores diligente, agirás de forma correta.”
