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".

Types of conditional sentence
There are various ways of classifying conditional sentences. One distinction is between those that state an implication between facts, and those that set up and refer to a hypothetical situation. There is also the distinction between conditionals that are considered factual or predictive, and those that are considered counterfactual or speculative (referring to a situation that did not or does not really exist).

Implicative and predictive
A conditional sentence expressing an implication (also called a factual conditional sentence) essentially states that if one fact holds, then so does another. (If the sentence is not a declarative sentence, then the consequence may be expressed as an order or a question rather than a statement.) The facts are usually stated in whatever grammatical tense is appropriate to them; there are not normally special tense or mood patterns for this type of conditional sentence. Such sentences may be used to express a certainty, a universal statement, a law of science, etc. (in these cases if may often be replaced by when):
If you heat water to 100 degrees, it boils.
If the sea is stormy, the waves are high.
They can also be used for logical deductions about particular circumstances (which can be in various mixtures of past, present and future):
If it's raining here now, then it was raining on the West Coast this morning.
If it's raining now, then your laundry is getting wet.
If it's raining now, there will be mushrooms to be picked next week.
If he locked the door, then Kitty is trapped inside.
A predictive conditional sentence concerns a situation dependent on a hypothetical (but entirely possible) future event. The consequence is normally also a statement about the future, although it may also be a consequent statement about present or past time (or a question or order).
If I become President, I'll lower taxes.
If it rains this afternoon, everybody will stay home.
If it rains this afternoon, then yesterday's weather forecast was wrong.
If it rains this afternoon, your garden party is doomed.
What will you do if he invites you?
If you see them, shoot!

Counterfactual
In a counterfactual or speculative conditional sentence, a situation is described as dependent on a condition that is known to be false, or presented as unlikely. The time frame of the hypothetical situation may be past, present or future, and the time frame of the condition does not always correspond to that of the consequence. For example:
If I were king, I could have you thrown in the dungeon.
If I won the lottery, I would buy a car.
If he said that to me, I would run away.
If you had called me, I would have come.
If you had done your job properly, we wouldn't be in this mess now.
The difference in meaning between a "counterfactual" conditional with a future time frame, and a "predictive" conditional as described in the previous section, may be slight. For example, there is no great practical difference in meaning between "If it rained tomorrow, I would cancel the match" and "If it rains tomorrow, I will cancel the match".
It is in the counterfactual type of conditional sentence that the grammatical form called the conditional mood (meaning something like the English "would ...") is most often found. For the uses of particular verb forms and grammatical structures in the various types and parts of conditional sentences in certain languages, see the following sections.

First conditional

"First conditional" refers to predictive conditional sentences (see above section); here, normally, the condition is expressed using the present tense and the consequence using the future:
If you make a mistake, someone will let you know.
If I study, I will pass the exam.

Second conditional

"Second conditional" refers to the pattern where the condition clause is in the past tense, and the consequence in conditional mood (using would or, in the first person and rarely, should). This is used for hypothetical, counterfactual situations in a present or future time frame (where the condition expressed is known to be false or is presented as unlikely).
If I liked parties, I would attend more of them.
If it were to rain tomorrow, I would dance in the street.
If I studied, I would pass the exam.
The past tense used in the condition clause is historically the past subjunctive; however in modern English this is identical to the past indicative except in certain dialects in the case of the verb be (first and third person singular), where the indicative is was and the subjunctive were. In this case either form may be used (was is more colloquial, and were more formal, although the phrase if I were you is common in colloquial language too):
If I (he, she, it) was/were rich, there would be plenty of money available for this project.

Third conditional

"Third conditional" is the pattern where the condition clause is in the past perfect, and the consequence is expressed using the conditional perfect. This is used to refer to hypothetical, counterfactual (or believed likely to be counterfactual) situations in the past
If you had called me, I would have come.
If I had studied, I would have passed the exam.
