Proper Adjectives

Okay, so what is this ? Does it mean that there are improper adjectives also? Of course, there are a multitude of them! Every abuse is one! In this case, we are referring to something quite different- we are referring to adjectives that refer to:-

•  a person's name, 
• a specific place or countries, 
• company names, 
• brands, 
• titles of books , movies, songs or other creative works, 
• names of religions,
• nationalities,
• months,
• days of the week and holidays.
