Explicação:
Há uma regra bem simples: quando a palavra começa com um som de vogal (A, E, I, O, U), então, use ‘AN’ – você vai perceber que pronunciar essas palavras fica até mais fácil com ‘AN’. E o contrário: quando a palavra começar com som de consoante, use ‘A’.
Assim, você usa ‘a’ com: “A ball” (uma bola), “A glass of water” (um copo de água) e “A cup of coffee” (uma xícara de café). Com essas palavras, você usa ‘AN’: “AN umbrella” (um guarda-chuva), “AN ice cream” (um sorvete) e “AN apple” (uma maçã).
