A severe critic is someone who harshly judges or evaluates something. The term can be broken down into four words: decrier (7 letters), rebuker (7 letters), SLATER (6 letters), and dutchuncle (10 letters). A decrier is someone who speaks out against something, a rebuker is someone who scolds or reprimands, a SLATER is someone who speaks ill of someone or something, and a dutchuncle is an older person who gives advice in a stern manner. Together, these words describe someone who is very critical and judgmental.
