1.NounThe act of logically entailing, the state of being entailed, or something that is entailed.
"Entailment does not imply causation: if a set of premisses entail a conclusion, that does not mean (necessarily) that they cause that conclusion to be true.; An argument hinges upon entailment whereas an if-then sentence hinges upon implication."
2.NounThe act of setting up an entail to restrict inheritance.
