The form "an" is always prescribed before words beginning with a silent h, such as "honorable", "heir", "hour", and, in American English, "herb". Some British dialects (for example, Cockney) silence all initial h's (h-dropping) and so employ "an" all the time: e.g., "an 'elmet". Many British usage books,[citation needed] therefore, discount a usage which some Americans (amongst others) employ as being a derivative of the Cockney.[citation needed] The reason is that the indefinite article a is pronounced either of two ways: as a schwa, or as the letter itself is pronounced, "long a" (actually a diphthong, /eɪ/). Some words beginning with the letter h have the primary stress on the second or later syllable. Pronouncing a as a schwa can diminish the sound of the schwa and melt into the vowel. Pronouncing it as a "long a" does not do this, but as the pronunciation cannot be prescribed, the word is spelled the same for either. Hence an may be seen in such phrases as "an historic", "an heroic", "an hôtel of excellence". Yet most English speakers would object to these uses, as the pronounced "h" is quite awkward following "an".
