Mentally unstable or deranged; removed from normal constraints or stability.
From un- + hinged, originally meaning 'removed from hinges' (like a door). The metaphorical sense of mental instability developed from the idea of losing structural support.
The metaphor of being 'unhinged' brilliantly captures how mental stability is like a door on its hinges - when the hinges fail, the door swings wildly and unpredictably, just as an unhinged mind operates without normal constraints.
Historically, 'unhinged' was applied disproportionately to women's emotional expression, medicalizing female anger and grief as mental illness; gendered psychiatric language pathologized women's resistance.
Avoid describing people as 'unhinged.' If discussing mental health, use clinical terms; if emotion, acknowledge anger/grief as valid. Reserve 'unhinged' for literal mechanical failure.

Women's rage at injustice was systematized as hysteria and insanity; feminist psychology recognizes anger as justified and healthy resistance, not pathology.
