Acyrologiaphobiac

An acyrologiaphobiac is someone with a fear of (or major aversion to) the improper use of words. This includes words that are "made up" or misheard, spelling errors, or homophones that are mistakenly substituted for the proper word. Common examples of this are using "loose" for "lose" or "reign" for "rein." Another frequently heard error is calling Alzheimer's Disease "Old timer's" disease.
