"Entail" refers to a legal term often used in property law, which restricts the inheritance of property to a specific line of heirs. This means that the property cannot be sold or passed on to someone outside of the designated family members. The purpose of entail is to keep the property within a family lineage, ensuring that it remains intact for future generations. In a broader context, "entail" can also mean to involve or necessitate something as a consequence. For example, a decision to move to a new city may entail finding a new job and adjusting to a different lifestyle. This usage highlights the connections between actions and their resulting obligations or requirements.
