皆無

1. Origins, structure, and basic meaning

• Structure: 皆無, read かいむ, combines all 皆 with absence 無 to denote complete nonexistence.
• Basic usage: It states emphatically that none of something exists, as in 証拠は皆無だ.

2. Common pitfalls and similar expressions

• Tone and register
  • Unlike 少ない, which means a small amount, it strongly sets the amount at zero and is unsuitable if any exists.
