It helps to observe the following rules:

• When we use two or more adjectives to describe the same person or thing, we use the article only before the first adjective.

EXAMPLE: He talked to a tall and blonde woman. (He talked to a (one) woman who was tall and blonde.)

• When we use two or more adjectives to refer to more than one person or thing, we use the article before each adjective.

EXAMPLE: He talked to a tall and a blonde woman. (He talked to two women, one of whom was tall and the other was a blonde.)
