Spanish Articles: Articles are special modifiers that appear before nouns or noun phrases. There are only two articles in the English language: the and a (and its variant, used before a word that starts with a vowel sound). A noun may also appear without an article in front of it. If you are a native speaker, you will probably know which article to place in front of a noun without having to think about it.
Here are some (The Articles):
The articles | Los artículos
There are three ways to refer to a noun: using (1) the definite singular. Eg.The lion is a majestic animal, (2) the indefinite singular A lion is a majestic animal, or (3) the indefinite plural. Eg. Lions are majestic animals
All three sentences convey the same meaning with slightly different emphasis. In spanish we have as well:
The indefinite article, un, una, unos, unas is used exactly like the English indefinite article a/an. It is used when referring to a single instance that is a part of a group that consists of many entities. The plural indefinite article, unos / unas is used when referring to more than a single entity.
Eg. Un actor – una actriz Un artista – una artista
The definite articles, el, la, los, las are basically equivalent to English the. Anytime the is used in English, a definite article will surely be used in Spanish. In some cases, however, Spanish will use a definite articles when English uses no article at all.
Eg. El actor – la actriz el artista – la artista
