Article
Does the noun need an article, and which one?
Meaning
Articles are small words used with nouns that help show which person or thing the speaker means. They can present something as identifiable, as one member of a group, or as a whole kind. Languages differ in when an article is required, optional, or absent. Languages without articles, such as Mandarin, use other words and context instead. Specific or general and New and known information describe meanings; articles are one way to help express them.
How to spot it
If a language has articles, look for recurring small words used with nouns to help show which thing is meant. Compare when they are needed and when a noun appears without one.
In your native language
English uses the definite article the for something the listener can identify and the indefinite article a/an for one member of a group. The choice between a and an depends on the next sound, not the next letter. A singular countable noun, a noun for one thing that can be counted, normally needs an article or another word such as my or this. Plural nouns and uncountable nouns, which name things not counted one by one (such as water), often occur without an article.
I found an old key in my bag.
An introduces one key and is used before the vowel sound in old.
Please close the door.
The situation makes it clear which door is meant.
Dogs need daily walks.
No article is used for dogs as a whole kind.
We swam in Lake Michigan.
The lake name has no article.
My sister is a nurse.
A singular job label normally needs a/an.
In your learning language
Spanish uses el/la/los/las for identifiable things and often whole kinds, and un/una/unos/unas to introduce an unspecified item or group. Articles match the noun's masculine or feminine group and its number; singular feminine nouns beginning with stressed /a/ normally take el or un directly before the noun, as in el agua fría. A singular countable noun usually needs an article or another specifying word, but an unmodified job or role after ser normally has no article.
He comprado una lámpara para el salón.
I bought a lamp for the living room.
Una introduces one lamp and matches the feminine noun lámpara.
Me gusta el café.
I like coffee.
The definite article is used for coffee in general.
Marta es enfermera.
Marta is a nurse.
A simple job label after ser normally has no article.
Learners whose language has no grammatical gender may choose an article by meaning rather than learning it with the noun. Learners whose language requires an article with job labels may add un/una where a noun without an article is usual.
