Artículos indefinidos. by Mind Map: Artículos indefinidos.

1. Use an when the indefinite article comes before a word beginning with a vowel sound: - An operation an idea an apple

2. Specific identity not known: Use the indefinite article a or an only with a singular count noun whose specific identity is not known to the reader. Use a before nouns that begin with a consonant sound, and use an before nouns that begin with a vowel sound.

2.1. Examples: 1) I think an animal is in the garage. 2) I own a cat and two dogs. 3) A boy, an apple. 4) An unhappy boy, a red apple. 5) An apple, some apples

3. In English, the two indefinite articles are a and an. Like other articles, indefinite articles are invariable. You use one or the other, depending on the first letter of the word following the article, for pronunciation reasons.

4. Here are some examples:

4.1. - a boy - an apple - a car - a helicopter - an elephant - a big elephant

5. Here are some exceptions:

5.1. - a hourglass (incorrect) - an hourglass (correct) - a honor (incorrect) - an honor (correct)

5.2. Likewise, there are some nouns beginning with a consonant that makes a vowel sound. In these cases, the indefinite article a should be used: an university (incorrect) a university (correct) an one-eyed pirate (incorrect) a one-eyed pirate (correctt)

6. Exceptions It’s important to note that not all nouns that begin with a consonant begin with the consonant sound. Always trust the sound, not the letter when applying the a vs. an rule. Remember, it’s about pronunciation.

7. How to use the indefinite articles a/an? The indefinite article an is used to make pronunciation easier when reading a text aloud. The general rule is to use a when the indefinite article precedes a word beginning with a consonant sound and an when it precedes a word starting with a vowel sound.

7.1. Use a when the indefinite article comes before a word beginning with a consonant sound: - A toy a book a house

8. Some rules for example.

8.1. Indefinite article a (before a singular noun beginning with a consonant sound) an (before a singular noun beginning with a vowel sound) Count nouns - refers to items that can be counted and are either singular or plural Non-count nouns - refers to items that are not counted and are always singular

9. Indefinite articles with Acronyms

9.1. These same rules apply to acronyms:

9.1.1. Examples: - A Society of Writers member was quoted in the article. (correct) - A S.O.W. member was quoted in the article. (incorrect) - An S.O.W. member was quoted in the article. (correct)
