  R \R\ ([aum]r).
     R, the eighteenth letter of English alphabet, is a vocal
     consonant. It is sometimes called a semivowel, and a liquid.
     See Guide to Pronunciation, [sect][sect] 178, 179, and
     250-254. ``R is the dog's letter and hurreth in the sound.''
     --B. Jonson.
  
     Note: In words derived from the Greek language the letter h
           is generally written after r to represent the aspirated
           sound of the Greek "r, but does not affect the
           pronunciation of the English word, as rhapsody,
           rhetoric. The English letter derives its form from the
           Greek through the Latin, the Greek letter derived from
           the Ph[oe]nician, which, it is believed, is ultimately
           of Egyptian origin. Etymologically, R is most closely
           related to l, s, and n; as in bandore, mandole; purple,
           L. purpura; E. chapter, F. chapitre, L. capitulum; E.
           was, were; hare, G. hase; E. order, F. ordre, L. ordo,
           ordinis; E. coffer, coffin.
  
     {The three Rs}, a jocose expression for reading, (w)riting,
        and (a)rithmetic, -- the fundamentals of an education.
