The condition of being an unmarried man.
He enjoyed the freedom of bachelordom before settling down.
Bachelordom is formed from "bachelor" (from Old French *bacheler*, meaning a young man or knight) and "-dom" (meaning state or condition). The word refers to the state or condition of being a bachelor, or an unmarried man.
Think of a young man ('bachelor') in a specific state ('-dom') of being unmarried — that's what bachelordom means.
