Which of the following sentences is correct?
"Many a girls was appearing in the examination."
"Many a girl was appearing in the examination."
The quick answer to the question is "Many a girl" is correct, and "Many a girls" is incorrect.
The fixed expression many a/an... is more formal than the single word many, and it is much less common. Many a/an... is used mainly in literary writing and newspapers. Like the adjective and pronoun many, many a/an... is used to indicate a large number of something. However, it takes a singular noun, which can be followed by a singular verb. Here are some examples:
- It remained a mystery for many a year. [=for many years]
- I've been there many a time. [=many times]
- Many a politician has promised to make changes. [=many politicians have]

If you want to say many a x, you need to use a singular noun. So many a girl would be correct. However, if you want, you could say many girls appeared / are appearing instead. if you take out the "a / an", many becomes plural and you can then use plural nouns like "girls" or "cars".
