Conditional Conjunctions in English Grammar

We use conjunctions to link other words, phrases, and clauses together. When it comes to conditional conjunctions, we use them as an alternative to the word if in any type of conditional sentence without changing the meaning of a sentence.

Some of the most common conditional conjunctions in English include provided that, providing that, as long as, unless, supposing, on condition that.

Rule 1: We can use the conditional conjunctions provided that, providing that, on (the) condition that in the meaning of only ... if.

Rule 2: We can use the conditional conjunctions as long as and so long as in the meaning of only ... if.

Rule 3: We can use the conditional conjunction unless in the meaning of if ... not.

Rule 4: We can use the conditional conjunction supposing in the meaning of what if.

Note: Keep in mind that you can switch the conjunctions in any type of conditional sentence.
