Certain words are often incorrectly used because of confusion resulting from similarity with other words in spelling or in meaning. The following deserve careful attention:

Although a is regularly used before words beginning with a consonant and an before words beginning with a vowel, when certain words written with an initial vowel are pronounced as though beginning with a consonant, a, not an, is used. Also, an, is used before words beginning with a silent consonant.

1. The term colloquial is frequently misunderstood. It refers to language suitable to familiar conversations; that is, it represents informality. Informality is just as correct as formality when it is appropriate to the occasion. Therefore, to mark an expression as colloquial is not by any means to condemn it, but simply to indicate the type of situation in which it may be used. Indeed, in every situation, colloquial expressions ( or colloquialisms ) are often appropriate than formal ones.
