I was looking at the definition of definite article and it reads like this - "The definite article is used before singular and plural nouns when the noun is specific or particular".
Since this definition is generally true so can we say that the definition can also be like this with no change in meaning-
1) The definite article is used before 'the' singular and plural nouns when the noun is specific or particular.
2) The definite article is used before singular and plural nouns when 'a' noun is specific or particular.
3) The definite article is used before singular and plural nouns when the nouns are specific or particular.
