I wonder if the word flood can be used as a flood. I think the word like water cannot be used as a water because it is a collective noun.
In my dictionary, it writes both countable and uncountable. But I'm not sure how I can use them apart. All the example sentences use the flood or floods or a [adjective] flood.
So when can the word flood be used as a flood and if so, when should I use it, instead of the uncountable form flood?
