A conditional sentence contains an independent clause and a dependent clause that almost always begins with “if”. A conditional sentence is a conditional sentence only if it contains both parts. A conditional sentence that expresses involvement (also known as a factual conditional sentence) essentially states that if one fact is true, another fact is true. (If the sentence is not a declarative sentence, the consequence may be expressed as an order or question rather than a statement.) Facts are usually given in the grammatical time that suits them; There is usually no particular time or mood for this type of conditional sentence. Such phrases can be used to provide certainty, a universal declaration, a law of science, etc. (in these cases, if it is often replaced by when): Explanation: For third suspended sentences, do not use a modal auxiliary verb in the if set. Some conditional clauses may begin with “when”. In each of the following examples, the expression printed in italics is a conditional clause. The sentence as a whole is a conditional sentence. Second conditional sentences are useful for expressing results that are completely unrealistic or unlikely to happen in the future.
Consider the following examples: There are a few things to keep in mind in the above sentences where the null condition is used. First, if the null condition is used, the correct tens to be used in both sentences are the simple present. A common mistake is the use of the simple future form. A predictive conditional theorem concerns a situation that depends on a hypothetical (but quite possible) future event. The consequence is usually also a statement about the future, although it can also be a coherent statement about the present or past time (or a question or order). Note that when using the third condition, we use past perfection (i.e. had + past partizip) in the if set. The modal auxiliary unit (would be, could, should, etc.) + have + partizip passed in the main clause expresses the theoretical situation that could have occurred. What is a third conditional sentence? A third suspended sentence expresses a past idea that did not happen.
The third suspended sentence expresses an imaginary result of this past event that did not occur. In other words, it`s unreal. Second, note that the words if and when can be used interchangeably in these zero-condition sentences. This is because the result will always be the same, so it doesn`t matter “if” or “when” it happens. The third conditional sentences are used to explain that the current circumstances would be different if something else had happened in the past. Consider the following examples: Consider these common mistakes when applying the third condition: Note that we use the simple present in the if clause and the simple future in the main clause, which is the clause that expresses the likely result. In this way, we point out that under a certain condition (as expressed in the if clause), a certain result is likely to occur in the future. Take a closer look at some of the most common mistakes people make with the first conditional structure: Let`s take a closer look at each of these different types of conditional sentences. In general, the simple future should only be used in the main section. An exception is if the action in the if clause takes place after the action in the main clause. Consider, for example, the following sentence: Linguists and philosophers of language sometimes avoid the term counterfactual because not all examples express counterfactual meanings. For example, the “Anderson case” has the grammatical form characteristic of a counterfactual condition, but does not mean that its precursor is false or unlikely.
  The sentence dependent on the first condition begins with “if” and uses the simple present tense. The clause independent of the first condition uses “will” plus the basic form of a verb. Conditional sentences are quite easy to identify, as they almost always start with “ifs”. You can also start with “when,” “assume that,” “give, that,” or “consider.” Conditional sentences in Latin are traditionally divided into three categories based on grammatical structure. Explanation: The third conditional mood expresses a situation that could only have occurred in the past if a certain condition had been met. That is why we use the modal auxiliary verb + have + the past partizip. Languages have different rules regarding the grammatical structure of conditional sentences. These may concern the syntactic structure of the previous and coherent clauses, as well as the forms of the verbs used in them (in particular their tense and mood). The rules for English and some other languages are described below; For more information, see the articles on the grammars of each language.
(Some languages are also described in the article on conditional mood.) Explanation: Use a modal auxiliary verb in the main sentence when using the second conditional humor to express the improbability that the result actually occurs. Define a conditional set: The definition of the conditional set is a type of sentence that expresses a condition and the result of the condition. Just like other sentences in English, a conditional sentence requires only one comma after the dependent sentence if the dependent sentence is placed before the independent sentence. Definition of Conditional Sentence: A set of conditional sentences is a type of sentence that specifies a condition and the outcome of that condition. Suspended sentences consist of a dependent clause and an independent clause that are linked to express this condition. Recently, the term X-Marked has been used as a substitute, with indicative conditions renamed to O-Marked conditions.    Under metalinguistic conditions, the precursor qualifies the use of a term. For example, in the following example, the speaker stated unconditionally that he had seen the person in question, whether that person really should be called her ex-husband or not.  Explanation: Use the null condition (i.e. simple present + simple presence) only when a certain result is guaranteed. If the result is likely, use the first condition (i.e. simple present + simple future).
