Just a question. If you had to write this sentence in the second conditional:

If the weather is bad, I won't go out.
If the weather was/were bad, I wouldn't go out

Use "were" in the second sentence.

Both are fine.

Correct! The sentence "If the weather is bad, I won't go out" can be written in the second conditional as "If the weather was/were bad, I wouldn't go out."

The second conditional is used to talk about hypothetical or unreal situations in the present or future. It often follows the structure "if + past simple, would + base form of the verb." In this case, "is" changes to "was/were" in the past simple tense, and "won't" changes to "wouldn't" (the contracted form of "would not") to express the hypothetical outcome of not going out.

To form the second conditional, follow these steps:
1. Start with the subordinating conjunction "if."
2. Use the past simple (in this case, "was" or "were") with the subject in the if-clause.
3. Use the modal verb "would" in the main clause.
4. Use the base form of the main verb (in this case, "go") after "would."

So, by applying these rules, we can rewrite the sentence using the correct form of the second conditional as "If the weather was/were bad, I wouldn't go out."
