VIII. OF THE LETTER H.
The sound of the consonant H, (though articulate and audible when properly uttered,) is little more than an aspirate breathing. It is heard in hat, hit, hot, hut, adhere.
H at the beginning of a word, is always sounded; except in heir, herb, honest, honour, hospital, hostler, hour, humble, humour, with their compounds and derivatives. H after r, is always silent; as in rhapsody, rhetoric, rheum, rhubarb. H final, immediately following a vowel, is always silent; as in ah, Sarah, Nineveh, Shiloh.
