- No article is used before proper nouns.
For example:
(a) Delhi is the capital of India.

But consider the following examples where an article is used before a proper noun.
(a) This man is a second Newton.

(b) I cannot forget the kindness with which he treated me.
Here the article is used before the abstract noun as the abstract noun has been qualified by an adjective or adjectival clause.
- No article is used before languages, subject of arts and science.
For example:
(a) We are studying English.
(b) Geometry is the toughest subject I have ever studied.
- No article is used before words such as school, college, church, bed, table, hospital, market, prison.

But if someone else’s mother is being talked about then the should be used.
For example: The mother would like to see you.
- Article should not be used before positions that are held at one time by one person only.
For example:
(a) S D Sharma was elected the president of the country. (Incorrect)
(b) S D Sharma was elected president of the country. (Correct)
- Please consider this sentence
(a) I have a black and white cat.
Here I mean that I have one cat that is partly black and partly white.
Now, consider its sentence
For example: I have two cats one is black and the other white.
Hence the rule is that when two or more adjectives qualify the same noun, the article is used before the first adjective only. But when they qualify different nouns, the article is used before each adjective separately.
Consider one more example.
(a) The President and Chairman is absent.
(b) The President and the Chairman are present.
Sentence a means that only one person is acting as president as well as chairman. Sentence b means that two different persons are acting as the President and the Chairman and both the persons are present.
