Using the Subjunctive in Sentences:

You usually see the subjunctive mood in sentences that express desire, doubt, emotions, or needs. For example:

• "I hope that he speaks French."
  • In Spanish: "Espero que él hable francés."

Important Grammar Tips:

• Passive Voice: You can use the subjunctive when the action is done by someone else.

  • For example: "I hope this is finished soon."
  • In Spanish: "Espero que esto sea terminado pronto."

• Conditionals: In "if" sentences, use the subjunctive for unlikely situations.

  • For example: "If I had money, I would travel."
  • In Spanish: "Si yo tuviera dinero, viajaría."

Getting used to these forms and learning when to use them will help you understand and express yourself better in Spanish.
