Knowra Writing system Writing system A writing system is a conventional set of visual signs and rules for representing language in written form. It determines how signs correspond to speech, meaning, or both.
Grapheme : A minimal functional unit of a writing system, such as a letter, character, or punctuation mark. Graphemes are the basic visual units assembled under a system’s conventions.
Alphabet : A writing system whose letters represent consonant and vowel sounds, individually or in combination. Alphabets map signs primarily to phonemes, making them one major system type.
Latin script : The alphabetic script used to write many languages, including English, Spanish, and Vietnamese. Its adaptation across languages shows how one script can serve distinct orthographies.
Cuneiform : A wedge-marked writing system used in ancient Mesopotamia for several languages. Its early development from accounting practices illuminates the emergence of writing.
Literacy : The ability to read and write in a language or other symbolic system. A system’s conventions determine what must be learned to become literate.
Phoneme : A speech sound category that distinguishes words in a particular language. Alphabetic systems commonly assign graphemes to phonemes.
Abjad : A writing system whose basic letters represent consonants, while vowels are omitted or marked secondarily. Abjads illustrate a consonant-centered way of representing speech.
Arabic script : A right-to-left script used for Arabic and adapted to write several other languages. Its abjad structure and contextual letter forms offer a contrasting design.
Egyptian hieroglyphs : The ancient Egyptian writing system combining signs with sound, word, and semantic functions. Its varied sign functions show that early writing was not simply pictorial.
Language planning : Deliberate efforts to influence a language’s use, form, or public status. Choosing or reforming a script can be part of planned language change.
