R

R, or r, is the eighteenth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ar (pronounced ), plural ars, or in Ireland or .

The letter ⟨r⟩ is the eighth most common letter in English and the fourth-most common consonant (after ⟨t⟩, ⟨n⟩, and ⟨s⟩).

The letter ⟨r⟩ is used to form the ending "-re", which is used in certain words such as centre in some varieties of English spelling, such as British English. Canadian English also uses the "-re" ending, unlike American English, where the ending is usually replaced by "-er" (center). This does not affect pronunciation.
