前所未有

النطق: qián suǒ wèi yǒu المعنى الحرفي: Before never having existed

الأصل والاستخدام

This idiom describes something that before (前) has never (未) existed (有). The phrase emphasizes absolute novelty - not just rare, but literally never before seen. It appeared in historical texts marking genuinely new developments that had no precedent. The idiom carries weight because it claims historical significance. Modern usage describes truly unprecedented events, achievements, or situations, though overuse has somewhat diluted its impact.
