Alphabet

An alphabet is a writing system in which each character represents a distinct sound (phoneme) of a language, whether a vowel or consonant. Its defining characteristic is that the number of signs is small—typically between 20 and 40 characters—and each character is derived from a meaningful word in the language.

The alphabet differs from other writing systems. Logographic systems (such as Chinese writing) use a character to represent a word or concept, not a single sound. Syllabic systems use characters to represent consonant-vowel units (a vowel and consonant combined). A true alphabet assigns characters to both consonants and vowels separately.

History of Development

Most alphabets in use today derive from Phoenician writing, which emerged on the eastern Mediterranean coast some three thousand years ago. That writing system was consonant-heavy: characters represented consonants, while vowels relied on the reader's knowledge. When the Greeks adopted this system, they modified some characters to represent vowels, creating a complete alphabet.

From Greek writing came the Latin alphabet and the Cyrillic alphabet. Arabic and Hebrew writing, by contrast, descend from a related branch of Phoenician, but they retained the consonant-heavy character, representing vowels through additional marks that are not always written.

Abjad and Abugida Types

Writing scholars distinguish different types. An abjad is a system that consistently writes consonants only, such as Arabic and Hebrew. An abugida is a system in which each character has a base consonant with vowels represented by small modifying marks, as in Devanagari script for Hindi. The term "alphabet," when used precisely, refers to a system that writes both vowels and consonants equally.

The Somali Alphabet

Somali is officially written in the Latin alphabet. This system uses Latin characters without additional diacritical marks, representing long vowels through doubling of characters (for example: aa, ee, ii, oo, uu). Before the adoption of the Latin script, other writing attempts for Somali existed, including native systems and the use of Arabic characters.

The Relationship Between Sound and Writing

No alphabet perfectly represents every sound of a language. In some languages a single character represents different sounds depending on its position in a word; in others, two characters combine to represent one sound (a digraph). Because the sounds of a language change over time while writing remains fixed, a gap always exists between spelling and pronunciation.
