To undermine something means to weaken or damage it, often in a secret, slow, or indirect way. You can undermine a person’s confidence or a plan’s chances of success.
From "under" and "mine," originally referring to digging tunnels under walls or buildings to make them collapse. The physical image turned into a metaphor for hidden weakening.
Medieval attackers literally "undermined" castles by digging under the walls until they fell. Today we use the same word for invisible social digging—gossip, doubt, or small rule‑breaking that eventually brings things down.
The verb is neutral, but it appears frequently in analyses of how women’s authority and credibility have been undermined in workplaces, politics, and science. This reflects patterns like interrupting, credit-stealing, and questioning competence more harshly for women.
When describing undermining behavior, focus on actions and structures rather than attributing them to stereotyped traits of any gender. Name specific practices (e.g., talking over colleagues) rather than vaguely blaming a gendered group.
When discussing how women’s authority has been undermined, highlight women who resisted or changed these dynamics, such as Shirley Chisholm in politics or Katherine Johnson in aerospace.
