It is related to the terms 'CYNICAL' (7 letters), 'INCREDULOUS' (11 letters), 'AGNOSTIC' (8 letters) and 'DISBELIEVING' (12 letters). A person who is CYNICAL is distrustful and has a negative outlook on life, while someone who is INCREDULOUS is unable to believe something due to its absurdity. An AGNOSTIC is someone who does not have a belief in any particular religion or deity, and a disbeliever is someone who does not accept something as true. All of these terms are related to scepticism, which is the attitude of doubting or questioning something.
