brittle

The word brittle describes something that is hard but easily broken or shattered. It implies a lack of elasticity; instead of bending or flexing under stress, a brittle material will snap or crumble. This applies to both physical objects and abstract concepts.

You might describe old bones as brittle—meaning they are fragile and prone to fracture. A brittle cookie snaps cleanly when you bite into it, unlike a chewy one that bends. But brittle isn't limited to things you can touch.

A brittle peace is one that's easily disturbed and likely to fall apart. A brittle argument is based on weak evidence and quickly collapses under scrutiny. Someone with a brittle ego might react defensively to even mild criticism, revealing an underlying insecurity. The term often suggests a hidden weakness beneath a seemingly strong exterior.

Historically, the word stems from the Old English brytel, which is derived from a root meaning "to break." This perfectly captures its core meaning of fragility and susceptibility to damage. So, whether you're describing a delicate piece of pottery, a tense political situation, or a sensitive personality, brittle conveys a sense of vulnerability and the potential for sudden breakage.
