I came across this expression in this newspaper article:
"It provides opportunity for a small nonprofit organization to be competitive with a major brand with huge marketing budget."
I was wondering whether it is instead more correct and/or appropriate the usage of an article before opportunity:
It provides an opportunity for a small nonprofit organization to [...].
To me, it sounds weird (incorrect?) using the singular noun opportunity without any article before it.
Do you have any feedback about it? Is it correct? Or maybe just used despite incorrect?
