If He Was or If He Were: Difference, Grammar Rules & Usage

Many English learners wonder whether they should say “if he was” or “if he were.” Although both expressions appear in English, they are not always interchangeable. The correct choice depends on whether you are talking about a real possibility or an imaginary, hypothetical situation. Understanding this difference will help you write and speak English more accurately and confidently.

If He Was or If He Were: Comparison Overview

The phrases “if he were” and “if he was” both introduce conditional clauses, but they serve different grammatical purposes.

• If he was is generally used for situations that may have actually happened or are considered possible.
• If he were is commonly used for hypothetical, imaginary, or contrary-to-fact situations.

Modern English sometimes allows flexibility in informal speech, but formal grammar still distinguishes between these two expressions.
