What is the male equivalent to a spinster?

The male equivalent to a "spinster" is often considered to be "bachelor." While "spinster" traditionally refers to an unmarried woman, "bachelor" denotes an unmarried man. However, the connotations of these terms differ; "spinster" can imply a social stigma regarding age and unmarried status, while "bachelor" is generally viewed more neutrally or even positively. In modern usage, both terms are becoming less common as societal views on marriage and singlehood evolve.
