Articles: A, An, The
Articles are words that define whether a noun is specific or unspecific.
1. Indefinite Articles: A / An
* Uses:
* To refer to a non-specific or general single noun.

* With certain numerical expressions (a hundred, a thousand).
* Before nouns indicating a profession or occupation.
* In exclamations with singular countable nouns (What a beautiful day!).
* "A" vs. "An":

* Use "an" before words that start with a vowel sound. Remember, it's about the sound, not just the letter!
* Examples:
* "I saw a dog in the park." (Any dog, not a specific one)
* "She wants to buy an apple." (Any apple)
* "He is a doctor."
