Explanation:

• Articles indicate if a noun in a sentence is general or specific. They describe if something is unspecific or specific. There are 2 types of article:
• The Definite Article (The): It describes the noun as something that is specific ( for example, something previously known/mentioned, or something unique, or something that is identified by the speaker), for example, This is the LPA University
• The Indefinite Article (A, An): A and an are called the indefinite articles. They describe the noun as something that is unspecific (example, something generic or something referred to mentioned for the 1st time), for example, Give me an orange. The indefinite article (an, a) is used for singular nouns and not used for plural nouns.
• If a word starts  with the vowel sound, then article to be used is an; else, if it starts with the consonant sound, the article to be used is a. Since hour is pronounced/said with h being silent, and with a vowel sound we write it as an hour.
