[Grammar] A song's tile : Love is a many splendored thing?

[vestcil]

Well, I have seen 'many a' before, but never seen 'a many' before.
Is 'a many' gramatically correct?
If it is correct, it should always be followed by singular noun, right?

 

[Rover_KE]

It's correct, and different from 'many a'.

The expression 'many-splendored' should more properly be hyphenated, as it is in about half of the entries on this page.
