I want to figure out the situation of the gerund that should I use adjective or adverb to modify it?
I know about the gerund that can function as both noun and action. It acts like a noun.
My first question is when the gerund is single and not talking about thing just use as noun(subject ..etc..) that we use adjective or adverb?!
Example : (Regular)(exercising) enhance one's self-confidence.(A noun) OR (Regularly exercising)enhance one's self-confidence.(A thing)
My teacher told me the answer is the firs form. But why ? Could somebody tell me a bit more specifically about gerund? I couldn't sleep a few days by this confusing problem, If some one can help me and give me some example with some explaining, that I'll be very grateful!!
