What term is used for a man who has lost his spouse due to death?

The term used for a man who has lost his spouse due to death is "widower." This designation specifically refers to a male who is mourning the loss of his wife. In the context of bereavement, the use of gender-specific terms helps to clearly define the relationship and the individual's status following the death of their spouse.

In contrast, the term "widow" refers to a woman who has lost her husband, thereby distinguishing the roles and experiences associated with each gender in the context of loss. Terms like "executor" and "executrix" relate to individuals appointed to administer a deceased person's estate and are not relevant to the status of being bereaved due to a spousal death. These distinctions are important in the field of mortuary administration as they guide appropriate language in grief counseling, documentation, and legal matters surrounding death and estates.
