Articles are words in English language that define a noun as specific or unspecific. The definite article is the world the which limits the meaning of a noun to one particular thing. The indefinite article takes two forms. It is the word a when it precedes a word that begins with a consonant whereas word an when it precedes a word that begins with a vowel. The indefinite article demonstrates a noun refers to a general idea rather than a particular thing. There are examples for illustrations of this concept.
