* [[Constant function|Constant]]: Is always true or always false regardless of its arguments.
* [[Monotonic function#In Boolean functions|Monotone]]: for every combination of argument values, changing an argument from false to true can only cause the output to switch from false to true and not from true to false. A function is said to be [[Unate function|unate]] in a certain variable if it is monotone with respect to changes in that variable.
* [[Linearity#Boolean functions|Linear]]: for each variable, flipping the value of the variable either always makes a difference in the truth value or never makes a difference (a [[parity function]]).
* [[Symmetric Boolean function|Symmetric]]: the value does not depend on the order of its arguments.
