I was struck by the difference in how we write and how we speak. For instance, in the written word, we use the indefinite article "an" (rather than "a") before words that begin with a vowel. All words beginning with a consonant are usually preceeded by the indefinite article "a" rather than "an." However, in the spoken word, this precedent does not always feel natural.
For instance, I was typing out the phrase "a SBC history" (short for "Southern Baptist Convention"). Now, if I were to say "a Southern Baptist Convention history," there would be no problem.
