kirjainjärjestelmä

A kirjainjärjestelmä, or alphabetic writing system, is a method of writing in which each sound in a language is represented by a distinct symbol, called a letter. These letters are then combined to form words. This is in contrast to other writing systems like logographic systems, where symbols represent entire words or morphemes, or syllabaries, where symbols represent syllables.

The development of alphabetic systems is generally considered a significant step in the history of writing. They are highly efficient because they require a relatively small number of symbols to represent a vast number of words. This makes learning to read and write more accessible compared to systems with thousands of characters. The concept of an alphabet likely originated in ancient Egypt or the Sinai Peninsula, evolving from earlier hieroglyphic systems.

The Phoenician alphabet is a crucial ancestor to many modern alphabetic scripts, including the Greek alphabet, which in turn influenced the Latin alphabet used for English and many other European languages. Alphabetic systems can vary greatly in their structure. Some are true alphabets where both consonants and vowels have dedicated letters, while others are abjads, which primarily represent consonants, or abugidas, where consonant symbols have an inherent vowel that can be modified. The principle of representing individual sounds, however, remains central to all forms of alphabetic writing.
