My question is how can I decide wheather a noun is a generic or specific one? I know all the rules but still one thing confuses me. For example:
"According to the linguist (mentioned before) inhabitants of certain communities share common experiences as well as knowledge".
Should I use "the" before "inhabitants" in this sentence? On the one hand, I refer to all inhabitants of these communities, therefore maybe it is generic reference and I should use zero article, on the other, I do not refer to all inhabitants in the world, only those of certain communities, than maybe it is specific reference.
Should I take only a noun or a noun phrase deciding wheater it is generic or specific?
