Mood and aspect as a system

The Core Idea

Mood shows the speaker stance toward the action, while aspect shows how the action unfolds. Seeing both together makes tense choice more coherent.
This is the conceptual map behind the verb system. Once mood and aspect are visible, individual tenses stop looking like isolated lists.

How It Works

1. Indicative usually presents facts, events, and assertions.
2. Subjunctive usually appears with uncertainty, desire, evaluation, condition, or non-asserted content.
3. Imperative expresses commands, invitations, and instructions.
4. Aspect asks whether the action is seen as complete, ongoing, habitual, beginning, repeating, or just finished.
5. Portuguese tense choice often reflects both mood and aspect at once, not just a calendar time label.
