Stab someone in the back
Meaning
To betray someone in a deceitful or treacherous manner, especially when they least expect it.
Origin
The phrase's roots are undeniably literal, conjuring a vivid image from an era where close-quarters combat and political intrigue were rife. To 'stab someone in the back' was a cowardly and treacherous act in medieval warfare or assassination, implying an attack from an unsuspecting position, often with a dagger. Unlike a frontal assault, which might involve a fair fight, a backstab was the ultimate act of betrayal, violating trust and chivalry. Over time, as literal daggers gave way to metaphorical ones in the courts and offices of the world, the image persisted, evolving into a powerful idiom to describe any profound act of disloyalty or deceit, capturing the shock and hurt of an unexpected betrayal.
