➤ When should I use articles with countable and uncountable nouns?
Use a/an with singular countable nouns when you mention them first (a student, an umbrella). Use the definite article the when both speaker and listener know the item (the book we read). Do not use a/an with uncountable nouns; use some, any, much, or a measurement instead.
