not firmly fixed; likely to change or fail
un- + stable, from Latin stabilis
Unstable means it's not stable - it might topple!
Historically weaponized against women: 'unstable' and 'hysterical' were used to dismiss women's legitimate concerns and justify medical abuse. Continues to be selectively applied to emotional expression coded feminine.
Use specific descriptors (inconsistent, variable, unpredictable) and avoid labeling people as inherently unstable, which carries gendered psychiatric stigma.
