关于冠词，鲁索说，Before a noun comes 'a', 'the' or nothing. This difference does not exist in Chinese and hence is difficult to learn. In Dutch this difference also exists and is almost - but not quite! -  the same as in English. 'Nothing' occurs more in English than in Dutch.

The determiners a/an and the are called "articles". They are the most common of all determiners. They come at the very beginning of a noun phrase. We divide them into "indefinite" and "definite" like this:

We use indefinite to mean non-specific. Indefinite is general. We use definite to mean specific. Definiteis particular. When we are talking about something in general, we use a or an. When we are talking about something in particular, we use the.

Think of the sky at night. In the sky we see MILLIONS of stars and ONE moon. So normally we would say:

• I saw a star last night.

• I saw the moon last night.

Look at some more examples:

Of course, often we can use a/an or the for the same word. It depends on the situation, not the word. Look at these examples:

• We want to buy an umbrella. (Any umbrella, not a particular umbrella.)

• It's raining! Where is the umbrella? (We already have an umbrella. We are looking for our umbrella, a particular umbrella.)

Articles with Countable and Uncountable Nouns

Notice that we use the indefinite article a/an ONLY with singular countable nouns: a dog, an egg, a very big man, an extremely delicious meal

By contrast, we can use the definite article the with ALL nouns: the dog, the eggs, the big men, the music, the food, the red wine

It is sometimes also possible to have no article at all—the so-called ZERO article. This can happen with all nouns (but normally not singular countable nouns): dogs, eggs, hot meals, music, red wine

The following table shows how we usually use articles with countable and uncountable nouns, but see EnglishClub Tip below for more about this.
