The Spanish Subjunctive is a strange concept to English speakers as it is very rarely used in the English language, in Spanish however it is used frequently. The subjunctive is a verb mood that is typically used to express a wish, emotion, opinion, judgement, possibility or something that has not yet happened and if you need further information regarding an explanation of how the subjunctive is used in Spanish there is a link at the end of this post that will help you.

This post, however, will provide the irregular conjugation of each of the tenses of the much used Spanish verb Ser in the subjunctive.

Subjunctive Present Tense (Subjuntivo presente)

• yo sea
• tú seas
• él/ella sea
• usted sea
• nosotros/as seamos
