A more thorough explanation:

Definition: An issue is a point of disagreement between different parties. In the law of trusts and estates, it refers to the lineal descendants of an individual, such as children, grandchildren, and great-grandchildren.

Example 1: The issue between the two political parties was whether or not to raise taxes.

Example 2: The deceased's will stated that his estate should be divided equally among his issue, which included his two children and four grandchildren.

These examples illustrate how the term "issue" can refer to a point of disagreement or a group of descendants in a legal context.
