Nouns - General and Specific

Do you mean common nouns (like 'city' and 'person') and proper nouns (like 'Chicago' and 'Mister Micawber')?

We call it general noun if the thing in area A, is the same with area B, and others, e.g. Cats are mammal. Cats here is general noun.
But if the thing is different from other, it's called Specific noun, e.g. My cat has a long tail. Cat here is a specific noun.

And what grammatical relevance does that have, Anon?

Mister Micawber,

analysing the class of nouns into general/specific and assigning these terms to them as their immanent features certainly does not have much to do with grammar as such, since this division is largely of theoretical interest to lexicology and semantics.

Besides, the division itself is decidedly unconventional - perhaps the author of the question could provide us

I see. Thanks, Gleb, but I hope it doesn't lead learners into writing sentences like the first, which should read:

Tragedy and comedy first appeared in Greece.

Mr Micawber,

your hopes may prove futile if learners carefully study one or two textbooks on the subject. From these they will learn that using the definite article in examples with 'tragedy' and 'comedy' conveys a formal tone in generic use. What is more, learners can even draw distinction between generic use (referring to the whole class) and general use (referring to in

using the definite article in examples with 'tragedy' and 'comedy' conveys a formal tone in generic use

It does not, Gleb, and your assertion that it does reveals that you are not a native speaker. Other members need to be aware that, in the face of your sesquipedalian garrulity, your advice is often very poor or downright incorrect.

People in 'prescriptive' houses shouldn't throw 'prescriptive' stones, Mr Micawber. For some unknown reason, you fancy yourself a greater authority on English than Randolph Quirk, Sidney Greenbaum and other prominent scholars, of whose numerous researches you have, unfortunately, never heard. Anyway, as the original Mister Micawber says: 'Something will turn up' - it is never too late to learn so

Generic vs. Specific belongs to Word Classes Based on Meaning . It is a way of explaining the meanings of nouns. A noun has "generic" meaning when it refers to things, people, ideas, etc., generally as types rather than as specific individuals. For example: color-pink (color is generic while pink is specific) season-summer employee-clerk

A general noun would be a regular noun that is vague. For example, an animal. I specific noun is a noun that is exact and not vague. For example, a cheetah.
