weak spot
Meaning
A particular area of vulnerability, either physical or metaphorical, that makes someone or something susceptible to attack or failure.
Origin
Imagine ancient fortifications, where architects meticulously planned defenses. Yet, even the most formidable wall could have a single, less-reinforced section – a literal "weak spot" that an invading army would relentlessly target. This concept, so starkly evident in physical structures and combat, easily migrated into the human realm. From a character's inherent flaw to a strategic vulnerability in a business plan, the phrase encapsulates that precise point of susceptibility, a tiny chink through which an entire system or person might be undone. It’s a timeless idea, simply expressed.
Examples
- The new security system seemed robust, but the IT expert quickly identified a weak spot in its firewalls.
- Despite his tough exterior, his love for his family was truly his weak spot.
