Usage notes

• As an emphasis or pro-verb, this term has in Spanish a usage that is not usually explicitly translated into English, since it could sound like a pleonasm, being that "positively", "affirmatively", and always related to a negation (explicit or not):

    He (positively) can, I cannot.

  • Esto sí es una fiesta.

    This sure is a party. / This is what I call a party.
