The act of involving or requiring something as a necessary part or consequence.
The entailment of the new policy will affect all employees.
Entailment → It is formed from "en-" (meaning to cause to be in) and "tail" (from Old French *tailler*, meaning to cut). The suffix "-ment" (meaning the action or result of) indicates the process or state of causing something to be cut or limited. Thus, entailment refers to the legal process of limiting the inheritance of property to specific heirs.
Think of 'causing to be in' ('en-') a state of 'cutting' ('tail') something down to specific heirs — that's what entailment means.
