Conditionals are a fundamental component of English grammar because they enable speakers and writers to express cause-and-effect relationships, possibilities, assumptions, and hypothetical situations. Means of expression of conditionals are as follows: complex sentences containing if-clause and main clause, elliptical forms, inverted forms, alternatives to if conjunctions (“unless,” “provided that,” “as long as,” and “suppose”) and so on. All means of expression of conditionals are used to describe a complex feature of conditionality in English.
