The statement that is NOT true about pronouns is:
"Demonstrative Pronouns are the same as the Demonstrative Adjectives except that they have an accent mark over the first 'e.'"
This statement is incorrect because demonstrative pronouns and demonstrative adjectives serve different functions despite having similar forms. Demonstrative adjectives modify nouns, while demonstrative pronouns replace nouns entirely and do not require an accent mark distinction based on their role.
