I'm writing a paper and I am not sure how to word this sentence. Which is the correct sentence:
I am able to avoid a pitfall into which many a student has fallen.
I am able to avoid a pitfall into which many a student have fallen.
I think the correct one is the first one since has agrees with student, but both sort of 'sound right' to me. Maybe because have agrees with many, you know? Can anyone tell me which is the correct wording?
