Had it not rained, I would have visited you. This means that

Analyze the question

The sentence "Had it not rained, I would have visited you" is a third conditional (past unreal conditional) written in inverted form. It asks what really happened in the past.

Explain the concept

The third conditional follows this pattern:

• If + past perfect, would have + past participle
• The inverted form drops "if" and puts "had" first: Had it not rained... = If it had not rained...

A third conditional always describes something that did not happen. The real situation is the opposite of what the sentence says:

• "It had not rained" (the condition) → in reality, it rained
• "I would have visited you" (the result) → in reality, I did not visit

Step-by-step solution

1. Rewrite the sentence in full: If it had not rained, I would have visited you.
2. Reverse the condition: it did rain.
3. Reverse the result: I did not visit.
4. Combine: It rained, so I did not visit you.

Check the options

• A. "I visited you even though it rained" says the visit happened, which is wrong.
• B. "It did not rain and so I visited you" says it did not rain, which is wrong.
• C. "It rained so I did not visit you" matches our reversal. ✔
• D. "Because it did not rain, I visited you" is wrong on both parts.

Answer: C

Tip: For third conditional sentences, remember "opposite of both parts." Whatever the sentence says, the reality is the reverse. This also works for inverted forms like Had I known... (= I did not know) and Had she studied... (= she did not study).
