Document Summary
Written language and reading is a sociocultural construct not biological as per the five requirement aforementioned like oral language. Reading and writing are species specific and requires stimulation from environment, but it is not universal, it does require instruction. Some languages are alphabetic where one letter represents a sound like english, some are syllabic where a symbol matches a syllable, like japanese and some are logographic where a symbol matches an entire word like in chinese. A grapheme is the smallest unit in written language that affects meaning. Each phoneme has a grapheme to represent it"s sound. Single grapheme represents many phonemes and one phoneme can be represented by many graphemes. We identify letters by the collection of lines and curves. Three levels; word level, 1st letter of word level, feature of letters level and they are all connected. Features present in the letter determines what letter gets activated and letters activated determine what words get activated.
