Hi fellow forum members,
Even though I'd say my English is pretty good, every once in a while I find myself confused on the proper use of certain words/grammatical structures. Just today, I found myself again wondering about when to include and when not to include the indefinite article a/an (a recurring issue for me it seems). I was writing and couldn't decide whether:
In this regard XXX, will serve as a case study allowing the student to blah blah blah
In this regard XXX, will serve as case study allowing the student to blah blah blah
Can anyone help me explain which one is correct and why?
