Note: that A / AN means "one" or "a single", so A/ AN cannot be used with plural nouns.
Examples:
LAW 4
If there is an adjective or an adverb-adjective combination before the noun, A(AN) should agree with the first sound in the adjective or the adverb-adjective combination.
Examples:
LAW 5
A before words such as "European" or "university" which sound like they start with a consonant even if the first letter is a vowel. Also Law A before letters and numbers which sound like they begin with a consonant, such as "U", "J", "1" or "9". Note:, it is the sound not the spelling which is important. For example, "1" is spelled O-N-E; however, it is pronounced "won" like it starts with a "W".
Examples:
LAW 6
Law AN before words such as "hour" which sound like they start with a vowel even if the first letter is a consonant. Also Law AN before letters and numbers which sound like they begin with a vowel, such as "F" or "8". Note:, it is the sound not the spelling which is important.

Examples:
LAW 7
Some words such as "herb" or "hospital" are more complicated becaLaw they are pronounced differently in different English accents. In most American accents, the "h" in "herb" is silent, so Americans usually say "an herb". In many British accents, the "h" in "herb" is pronounced, so many British say "a herb". In some British accents, the "h" in hospital is silent, so some British say "an hospital" instead of "a hospital".
LAW 8
Some nouns are considered uncountable like: information, air, advice, salt and fun, etc. so A/AN is not used in these cases:
Examples:
LAW 9
A and AN are indefinite articles. "Indefinite" means "not specific". Law A(AN) when you are talking about a thing in general, NOT a specific thing.
Examples:
when talking about a thing which is new, unknown, or introduced to a listener for the first time. Also when you are asking about the existence of something.
Examples:
Similarly, Law A(AN) to introduce what type of thing we are talking about.
Examples:
Note: You cannot Law A(AN) with plural nouns; as Law A(AN) means "one" or "a single".
Examples:
LAW 10
THE is called a definite article. "Definite" means "specific". Law THE when talking about something which is already known to the listener or which has been previously mentioned, introduced, or discussed.
Examples:
LAW 11
Many clauses and phrases make the noun known to the listener by telling the listener which person or thing we are talking about. Let's look at an example sentence:
Law THE in this sentence: The phrase "on the table" tells the listener which key we are referring to. We are not talking about other key, we are talking about a specific book that the listener can see or already knows about.
Examples:
N.B: Not all clauses and phrases make the noun known to the listener. Some clauses do not introduce noun to the listeners or readers and simply add some extra bit of information.
