How do you differ a an the in English grammar?

The words "an" and "the" are both articles in English grammar. They are used to indicate whether the following noun is specific or general.

Use "an" before a word that begins with a vowel sound.

- For example: an apple, an orange, an umbrella

Use "the" before a word that begins with a consonant sound.

- For example: the book, the table, the chair

There are a few exceptions to these rules.

- For example, we use "the" before a vowel sound when the noun is specific.

- For example: the apple (a specific apple that has been mentioned before)

- We also use "an" before a consonant sound when the noun is uncountable.

- For example: an ice cream (ice cream is an uncountable noun because we can't count individual scoops of ice cream)

Here is a table summarizing the use of "an" and "the":

| Noun | Article |

|--------------------|----------|

| Apple | an |

| Orange | an |

| Umbrella | an |

| Book | the |

| Table | the |

| Chair | the |

| The apple | the (specific) |

| An ice cream | an (uncountable) |
