The number of letters in the Latin alphabet has varied. When it was first derived from the Etruscan alphabet, it contained only 21 letters. Later, G was added to represent , which had previously been spelled C, and Z ceased to be included in the alphabet, as the language then had no voiced alveolar fricative. The letters K, Y, and Z were later added to represent Greek letters kappa, upsilon, and zeta respectively, in Greek loanwords.
