Unit 6.1

Alternatives to If



A conditional sentence is usually composed by two parts: the If-clause (or conditional clause) that expresses the condition, and the main clause that expresses the consequence of that condition.

We have different structures for conditionals. {see Zero Conditional and First Conditional A2 level, Second Conditional and Third Conditional B1 Level}

There are other conjunctions that we can to introduce conditionals.


The alteranatives to If are: but for, even if, if in doubt, if it weren’t for/if it hadn’t been for, if necessary, if not, if possible, if so, in case, only if, providing/provided (that), so/as long as, suppose/supposing, unless, what if, when…

We use the conjunctions that introduce conditions in the following cases:

  1. Even if: it emphasises that something will happen, would happen or would have happened whatever the condition is/were;
  2. If it weren’t for/if it hadn’t been for, but for: these expressions mean without; they are used in second and third conditionals and are usually followed by usually precede a noun phrase;
  3. If in doubt, if possible, if necessary… : we can make the if-clause shorter, by omitting the subject and the verb be; in certain idiomatic expressions, the subject and be are normally omitted;
  4. If so, if not: they can stand for an if-clause depending on the context;
  5. In case and if: an in case-clause gives a reason, while an if-clause describes a condition. We can use should after in case.
  6. Only If: it makes the condition more restrictive; if the if-clause is first, the subject and the auxiliary in the main clause are inverted;
  7. So/as long as, providing/provided (that): we can use them instead of if to express a condition; note that providing/provided (that) is a bit formal.
  8. Suppose/supposing, What if: they can replace if, mainly in everyday conversation, and are often used without a main clause;
  9. Unless: it appears before an affermative verb to express if … not.
  10. When: it can replace if in zero conditionals; in the other types of conditionals, we cannot use when instead of if;
