trueism

Example:The statement that 'every beginning is difficult' is a paradox given the well-known truism that 'practice makes perfect.'

Definition:A statement or situation that seems to be contradictory or opposed to common sense but is actually based on a revealed truth or a hidden fact.

Example:Some parents wrongly believe that infants need constant attention, but that is a fad, not a truism.

Definition:A short-lived fashion or trend, not necessarily lasting very long, often used in a derogatory manner to denote something as unimportant or trivial.
