A statement is a declarative sentence that is either true or false, such as 'The sky is blue.' A predicate is an expression that contains a variable and becomes a statement when the variable is specified, such as 'x is greater than 5.' Predicates provide a way to discuss properties that apply to different subjects, whereas statements assert specific facts.
