Mood refers to verb forms that express the speaker’s attitude toward an action, such as certainty, desire, or possibility. In Portuguese, the main moods are the indicative (e.g.: Já me vou), the subjunctive (e.g.: Quero que vás), and the conditional (e.g.: Gostaria de ir).
The imperative is also considered a mood.
Like tense, mood is expressed through changes in the verb form, including endings and, in some cases, stem changes.
