Identifying Articles Part 2

Determiners are used to modify a noun. This function is generally performed by articles, demonstratives, and quantifiers.
 

The words “a, an, and the” are articles. They come at the beginning of a noun phrase.
 

A and an are used when talking about something unspecific. Use a before words starting with consonant sound. Use an before words starting with vowel sound.
 

I want a pen. [any pen]

I have an umbrella. [any umbrella]
 

The is used when talking about something specific.
 

Have you washed the car? [specific car]
