*Conditional use means that an action depends on another. Conditionals are used to discuss real or unreal. In general, conditional sentences have the word "if" (si).
Note that there is no conditional tense for English and in Spanish there. At the same time, use the auxiliary verbs "would" to form the conditional in English.
There are four types of conditional sentences and the use of one over another reflects the likelihood of action.
1 Zero Conditional (Type 0)
This type is used when the condition of the conditional and the result is always true, such as scientific facts.
IF Condition Result
Present simple Present simple if
* Examples:
* If you heat water to 100 ° C, it boils. / Water boils if you heat it to 100 ° C. (If you heat water boils at 100 ° C).
* If I do not practice the piano everyday I play poorly. / I play the piano poorly if I do not practice everyday. (If you do not practice the piano every day I play bad.)
* Does your mom get mad if you do not call her? / If you do not call your mom, does she get mad? (If not call your mother, get angry?)
Note: We can change the order of the sentences without changing the meaning. Also, in general with this type of conditional, we can replace "if" to "when" without altering the meaning.
2 ) First Conditinal (Type 1)
This type of conditional uses for the future and in cases where it is likely that the condition will pass.
IF Condition Result
If simple Present simple Future ("will")
* Examples:
* If Bill studies, He Will pass the exam. / Bill Will pass the exam if I studies. (If Bill studies, passing the exam.)
* If It Does not Rain, We Will go to the beach. / We will go to the beach if it Does not rain. (If it rains, go to the beach.)
* Will you take the train if you miss the bus? / If you miss the bus, the train will you take? (¿Take the train if you miss the bus?)
Note: You can use some modal verbs instead of "will" to change the probability or express an opinion. For more information, see the lesson on modal verbs.
* Examples:
* If It Does not Rain, May we go to the beach. (* With the use of "may", the meaning of this phrase changes. Now, the speaker recognizes that you can go to the beach but not so sure if it will go.)
* If It Does not Rain Should we go to the beach. (* In this case, the use of "should" expresses the opinion of the speaker.)
* If It Does not Rain Can we go to the beach. ("Can" means you can go to the beach, but does not indicate the probability.)
3 ) Second Conditional (Type 2)
Type 2 is used to express an unrealistic possibility in the present, as a wish or a dream, or an action in the future is not likely.
IF Condition Result
If Past simple "Would" + infinitive
* Examples:
* If I won the lottery, I Would Travel Around the World. / I Would Travel Around the World if I won the lottery. (If you win the lottery, travel around the world.)
* If more time HAD Rachel, Would she learn to play the guitar. / Rachel Would learn to play the guitar if She Had more time. (If Rachel had more time, learn to play guitar.)
* Would you be happy if You Were to get married? / If You Were to get married, would you be happy? (Would you be happy if you married?)
Note: As in the type 1 can use other modal verbs instead of "would" to change the meaning and possibility.
4) Third Conditional (Type 3)
In contrast to types 1 and 2, using the third type of probation when it comes to a condition in the past that has not sucedidio.
IF Condition Result
If Past perfect "Would have" + past participle
* Examples:
* If I had Known Then What I know now, I Would Have Done Things Differently. / I Would Have Done Things Differently If I Had Known Then What I Know now. (If I had known in the past what I know now, would have done things differently.)
* Suzanne Would Have Had the heart attack if she HAD gone on a diet as her physician recommended. / If Suzanne HAD gone on a diet as her physician recommended she Would Have Had the heart attack. (Suzanne had not had the heart attack if he had made diet and your doctor recommended.)
* Would You have liked to go to university if You Had Been Able to AFFORD it? / If you had Been Able to AFFORD it, would you liked to go to Have university? (Would you like to go to college if you had allowed you to pay?)
Note: As the types 1 and 2, you can use other modal verbs instead of "would" to change the meaning and probability.
