Dysorthography is a difficulty in writing which manifests itself in the making of various types of errors: typical spelling errors, resulting from a failure to follow the spelling rules known to the pupil, and specific errors such as confusion of letters (substitution), omission, addition of letters and syllables, mirroring letters and numbers. Dysorthographies are diagnosed in pupils with normal mental development, in cases where difficulties occur despite knowledge of spelling rules, absence of sensory defects and educational neglect.
