名詞

nonsister (複数形 nonsisters)

1. One who is not a sister.
   • 2019, Sarah M. S. Pearsall, Polygamy: An Early American History (page 57)

     While this point may have been an exaggeration, it does seem that for nonsisters, the first wife enjoyed considerable status, while subsequent wives, some of whom may have been “chore” or captive wives, had less.
