Spanish articles

Spanish definite articles

Definite articles are used to indicate a specific noun and they often correspond to the  English the. However, in many instances where the definite article is necessary in Spanish, it is omitted in English. 

Masculine forms

• El chico de la puerta a lado se llama Miguel. (The name of the boy who lives next door is Miguel.)
• Los chicos de la puerta a lado son gemelos. (The boys who live next door are twins.)

Femenine forms

• Me encanta la comida italiana. (I love Italian food.)
• Me gustan las zanahorias. (I like carrots.)

Spanish indefinite articles

In both Spanish and English, indefinite articles refers to one individual out of a general group. In their singular form, they often correspond to the English "a, an", while in their plural form, they stand for "some, a few". 

Masculine forms

• Tengo un abrigo nuevo. (I have a new overcoat.)
• Hay unos perros en el patio de mi abuela. (There are a few dogs in my grandmother's courtyard)

Femenine forms

• Tengo una falda nueva. (I have a new skirt.)
• Compramos unas peras. (We bought some pears.)

Spanish lo - the neuter article

Spanish has a "third gender", which is expressed by the neuter article lo. This form is invariable and it is mostly used to communicate an abstract idea.

Example:

Lo importante es que hayas llegado bien a casa. (What matters / The important thing is that you have arrived home safely.)
