R.
R has the same rough snarling sound as in the other tongues.
The Saxons used often to put h before it, as before l at the beginning of words.
Rh is used in words derived from the Greek, as myrrh, myrrhine, catarrhous, rheum, rheumatick, rhyme.
Re, at the end of some words derived from the Latin or French, is pronounced like a weak er, as theatre, sepulchre.
