CONDITIONALS

CONDITIONALS 



Conditional tenses are used to speculate about what could happen, what might have happened, and what we wish would happen. In English, most sentences using the conditional contain the word if. Many conditional forms in English are used in sentences that include verbs in one of the past tenses. This usage is referred to as "the unreal past" because we use a past tense but we are not actually referring to something that happened in the past. There are five main ways of constructing conditional sentences in English. In all cases, these sentences are made up of an if clause and a main clause. In many negative conditional sentences, there is an equivalent sentence construction using "unless" instead of "if".

zero conditional

The order of the two sentences that make up the structure of the conditional can be changed. If we start with the condition (If), we will separate them with a comma. If we start with the phrase that expresses the result, it is not necessary to put the comma.




First conditional

In English there are several types of conditional, among them, the first conditional. This type of conditional is used in situations in which if a condition is met, a given result is likely to occur.



second conditional

We use a past verb though are imagining the present or the future to be different.
The second clause of subject + would + verb (conditional verb) is conditional to the first clause happening (or will only happen if the first part/clause happens).
Example: If I won the lottery, I would travel around the world.
 It is unlikely that I will win the lottery, but I'm going to hypothetically imagine that I did win. In that situation I would travel around the world. So in order for me to travel around the world, I would need the first clause (the condition or situation) to happen, that is, for me to win the lottery first.

Third conditional
The first conditional and second conditionals talk about the future. With the third conditional we talk about the past. We talk about a condition in the past that did not happen. That is why there is no possibility for this condition. The third conditional is also like a dream, but with no possibility of the dream coming true.
