Fundamental Strategies of Writing Systems

Key Insight

Writing systems fundamentally employ three strategies, differing in the size of the speech unit denoted by a single written sign: a single basic sound, a whole syllable, or a whole word. The alphabet, the most common strategy today, ideally assigns a unique letter to each basic sound (phoneme). However, most alphabets, including English which uses 26 letters for approximately 40 phonemes, have fewer letters than phonemes. Consequently, they assign multiple phonemes to the same letter or represent some phonemes with combinations of letters, such as 'sh' and 'th' in English.

The second strategy utilizes logograms, where one written sign represents an entire word. This approach is prevalent in Chinese writing and the Japanese kanji system. Historically, logographic systems were more widespread before the advent of alphabetic writing, including Egyptian hieroglyphs, Maya glyphs, and Sumerian cuneiform. The third strategy, syllabaries, uses a sign for each syllable. Most syllabaries provide distinct signs for syllables consisting of one consonant followed by one vowel (e.g., 'fa-mi-ly') and employ various methods for other syllable types. Ancient examples include Mycenaean Greek Linear B, and modern examples include the Japanese kana syllabary.

No actual writing system is purely exclusive to one strategy. For instance, Chinese writing is not solely logographic, nor is English writing purely alphabetic. English, like other alphabetic systems, incorporates many logograms such as numerals, '$', '%', and '+', which are arbitrary signs representing whole words without phonetic elements. Similarly, 'syllabic' Linear B included numerous logograms, and 'logographic' Egyptian hieroglyphs contained many syllabic signs, as well as a virtual alphabet of individual consonant letters, demonstrating the mixed nature of most writing systems.
