Brazilian Portuguese subjunctive: espero que and duvido que

Learn the form inside a useful frame

Rather than treating mood as an isolated ending, connect it to the expression that introduces the clause. A wish or expectation commonly takes a subjunctive complement. The time of the event may still be in the future.

Espero que a visita seja interessante.

I hope the visit is interesting.

Doubt is a stance, not a proof

A sentence expressing doubt tells us about the speaker’s attitude. It does not by itself prove the opposite proposition. Likewise, an indicative form is not a guarantee that a claim has been independently checked.

Duvido que o plano funcione.

I doubt that the plan works.

Keep meaning and form separate

The same mood can occur in a reaction to an event the speaker accepts as real. Later compound forms also distinguish prior completion. Avoid replacing those distinctions with the shortcut that subjunctive always means imaginary.

Lamento que ela esteja doente.

I regret that she is ill.

Practise, then recall it later

The matching grammar block includes guided practice, a separate mastery check and spaced review. The first 10 blocks of each course are free; other available blocks require course access or an eligible trial.
