Conditional

1) Express an action that you would do if something else were possible

    Iría al cine si tuviera dinero. - I would go to the movies if I had money.

2) A conditional desire

  Me gustaría tomar una limonada. - I would like to have a lemonade.

3) An indirect quotation

    María dijo que vendría mañana. - Mary said that she would come tomorrow.
    María decía que vendría mañana. - Mary was saying that she would come tomorrow.

Note: In the first sentence you use the preterite tense of "decir - to tell" because the action was completed in the past.   In the second sentence you use the imperfect indicative tense of "decir - to tell" because the completion of the action is not indicated.

4) Conjecture regarding the past

    ¿Quién sería? - I wonder who that was. 

5) Probability regarding the past

   Serían las cinco cuando salieron.  - It was probably five o'clock when they went out.

Note: You use the preterite tense of "salir - to go out" because the action was completed in the past.

Test yourself on the following "-ir" verbs: "escribir - to write", "recibir - to receive" and "vivir - to live".  Once you think you know the answer place your cursor over the box and drag it to the right to reveal the answer.

Note:  It can get a little confusing when you are using the word "si" to mean "if".  When you are using "if" you are generally constructing an "if - result" statement.  By this you mean that if something does exist  you will do something or if something had existed you would have done something.  For example you may say "If I have money I will go to the movies." - "Si tengo dinero, iré al cine."  In this case you would use the present tense of "tener - to have" and the future tense of "ir - to go".  But what if you say "If I had money I go to the movies." - "Si tuviera dinero, iría al cine."  In this case you would use the imperfect subjunctive tense of "tener - to have" and the conditional tense of "ir - to go".
