Nondogmatic → It is formed from "non-" (meaning not) and "dogmatic" (from Greek "dogma", meaning belief or opinion). The word "nondogmatic" means not adhering to a fixed set of beliefs or doctrines.
Think of 'non-' meaning not, and 'dogmatic' relating to beliefs — so nondogmatic describes a way of thinking that is not bound by strict beliefs.
