English grammar - ~ing usage
I want to know that when we add ing to a word what happens to it? Is it become a noun or an adjective? For instance when we say "overwhelming experience" in this case -ing creates an adjective and when we say "it causes overcrowding" it creates a noun. Also i want to know if it can create a noun or an adjective for a word. Like can we say "overcrowding areas" and hence using word+ing as a noun or an adjective.
You're right. Adding -ing can make either an adjective or a noun. But I've never heard "overcrowding areas." It would be more usual to say "areas of overcrowding" or "overcrowded areas."
