Aprendizaje rápido
Los artículos muestran si un sustantivo es uno entre muchos, uno concreto que el oyente puede identificar o una categoría general.
Recuerda
- a y an presentan algo nuevo y contable: I bought a lamp.
- the señala algo ya identificable: the lamp is broken.
- Sin artículo con plurales e incontables en afirmaciones generales: lamps are cheap.
Ejemplos
- 1I bought a fresh sandwich and an apple for lunch at the bakery.
- 2The sandwich was delicious, but the apple was slightly sour.
Error común que evitar
a y the suelen ser las dos gramaticales; lo que decide es la frase alrededor del sustantivo. Si nada ha presentado aún el sustantivo, the suele estar mal.

Three choices
Articles tell the listener whether you are referring to something general or something specific. English has three possibilities:
A and an
(1) Indefinite Article (A / An): Used with singular countable nouns when introducing an item for the first time or referring to any member of a group.
- I bought a book
- She ate an apple
Use A before consonant sounds: a pen, a house, a table, a university (the letter 'u' produces the /j/ consonant sound), a European city. Use AN before vowel sounds: an egg, an orange, an umbrella, an hour (the letter 'h' is completely silent), an honest person.
The
(2) Definite Article (The): Used with singular, plural, or uncountable nouns when both speaker and listener know which specific entity is meant. This happens when the item was already mentioned ("I bought a shirt and a hat. The shirt is blue"), when unique in the world ("the sun", "the moon"), or identified by context ("the front door").
No article
(3) Zero Article (No article): Used with plural countable nouns and uncountable nouns when making general statements:
- Cats are friendly animals
- Milk contains calcium
- Music brings joy
Plural nouns
Plural nouns: Most nouns add -s (books, cars). Nouns ending in -s, -x, -ch, -sh add -es (buses, boxes, matches). Nouns ending in consonant + y change to -ies (cities). Irregular plurals must be memorized: child → children, person → people, man → men, woman → women, tooth → teeth.

How to read this A1 topic
At A1, aim for one clear sentence: subject, verb, agreement, and a simple complement.
1. Find the subject
English normally needs an explicit subject before the verb.
It is cold.
2. Check the verb form
Be, have, and third-person -s carry a lot of early grammar.
She works here.
3. Keep a model sentence
Learn one short pattern and swap the words carefully.
I am a student.
Articles and quantity
English articles depend on countability, specificity, and whether the listener can identify the noun.
| Meaning | Count singular | Count plural | Uncountable |
|---|---|---|---|
| first mention | a book | some books | some water |
| known / specific | the book | the books | the water |
| general | a tiger / the tiger | tigers | water |
| negative quantity | no book / not a book | no books / not any books | no water / not any water |

Excepciones
Proper names of individual countries, cities, and streets take no article (Spain, Tokyo, Baker Street). However, countries that are plural or political unions require the (the United States, the United Kingdom, the Netherlands). Meals take no article in general usage ("have breakfast", "eat lunch"). Fixed institutional locations also drop the article in phrases of function: "at school", "at work", "at home", "in bed", and "go home".
