R is the eighteenth letter of the Latin alphabet.

Semitic Rêš (the head) developed into Greek Ρω (Rô). The sound value /r/ however was maintained in Greek as well as Etruscan and Latin. The finishing stroke was added to the Greek Rho to distinguish it from a later form of the Greek Pi, at a time when there were only capital letters in Latin. It is usually one of the liquid consonants, though there are many ways it is pronounced in European languages.
