- I had to try, didn't I?
or
- I had to try, hadn't I?
Which one is correct? If both sound awkward, could you please tell me the correct answer?
Thank you in advance!
In modern standard English, "have" in "have to" is generally treated as a lexical verb, not as an auxiliary: eg. "I didn't have to try" (cf. the less idiomatic *"I haven't to try").
So in this case you need to add the dummy auxiliary "do" and "have" cannot be in the question tag:
"I had to try, didn't I". ✅
