Did you note…? Its conjugation is very similar to the past indicative mood form. Keep this tip in mind!

Does the subjunctive mood have another past tense and a future tense? Yes, it does, but it isn’t frequently used in spanish. So we can’t jump it!

Imperative Mood

SubjectPositiveNegative
No seas
UstedseaNo sea
UstedesseanNo sean

This form is used to give commands. The commands are given to other people, that’s why it needs to be conjugated only with tú, usted, ustedes.

For example:

  • bueno con tu hermana.-Be nice to your sister.
  • No seas malo con tu hermana.-Don’t be mean to your sister.
  • Sea amable.-Be kind.
  • No sea grosero.-Don’t be rude.
  • Sean amables.-Be kind.
  • No sean groseros.-Don’t be rude.
