Pedant facet of pedantry
Medical conditions
Obsessive–compulsive personality disorder (OCPD) is in part characterized by a form of pedantry that is excessively concerned with the correct following of rules, procedures, and practices. Sometimes the rules that OCPD sufferers obsessively follow are of their own devising, or are corruptions or reinterpretations of the letter of actual rules.
Pedantry can also be an indication of specific developmental disorders. In particular, people with Autism Spectrum Disorder (formerly Asperger syndrome) often have behaviour characterized by pedantic speech.
