Set of symbols or characters that represent language's sounds in writing. Each character usually represents a simple vowel, a diphthong (two vowels), or one or two consonants. A writing system in which one character represents a whole syllable is called a syllabary. The first alphabet is believed to have been the North Semitic, which originated in the eastern Mediterranean region between 1700 and 1500 BC. Alphabets that arose in the next 500 years included the Canaanite and Aramaic, from which the modern Hebrew and Arabic alphabets descended, and the Greek (ancestor of the Latin alphabet), considered the first true alphabet because it includes both consonants and vowels. Scholars have attempted to establish an exact correspondence between each sound and its symbol in new alphabets such as the International Phonetic Alphabet.
