What is the primary focus of the abbreviation d.s.p.?

The abbreviation d.s.p. stands for "deceased, sine prole," which is a Latin phrase meaning "deceased without offspring" or "died without issue." In contexts such as wills and estates, this term designates an individual who has passed away and has no living descendants or children. Therefore, focusing on progeny or offspring is the central theme of this abbreviation, as it specifically indicates the absence of descendants in the context of the individual’s estate and inheritance matters. The other options do not accurately reflect the specific meaning of d.s.p. related to the absence of heirs.
