how many articles are there in english language
The articles in English grammar are the and a / an, and in certain contexts some. "An" and "a" are modern forms of the Old English "an", which in Anglian dialects was the number "one" (compare "on" in Saxon dialects) and survived into Modern Scots as the number "owan". Both "on" (respelled "one" by the Norman language) and "an" survived into Modern English, with "one" used as the number and "an" ("a", before nouns that begin with a consonant sound) as an indefinite article.
