Conditional sentences in Spanish are all about what could happen if certain things are true. Let’s break this down into simpler parts:

1. Structure:

   • Si + Present Indicative, Future Indicative: This is for real situations that could happen.
     • Example: Si estudias, pasarás el examen.
     • (If you study, you will pass the exam.)
   • Si + Imperfect Subjunctive, Conditional: This is for situations that are not very likely to happen.
     • Example: Si tuviera dinero, viajaría.
     • (If I had money, I would travel.)

2. Conjugation:

   • Use the correct form of the verb based on when you are talking about:
     • Present Indicative: (hablo, comes - I speak, you eat)
     • Imperfect Subjunctive: (hablara, comiera - I spoke, I ate)
     • Conditional: (hablaría, comería - I would speak, I would eat)

3. Important Notes:

   • Make sure the verb matches the subject in gender (male or female) and number (singular or plural).
   • Be careful with irregular verbs to make sure you get the right form.

By following these rules, you can make sentences about what might happen based on different situations!
