最悪

1. Origins, structure, and basic meaning

• Structure: 最悪 is read as さいあく and is a noun and adjectival noun for the worst possible state or evaluation.
• Basic usage: Use 最悪だった to evaluate an experience and 最悪の事態 with の to modify a noun.

2. Common pitfalls and similar expressions

• Form to remember
  • Before a noun, 最悪の事態 is the standard pattern rather than treating it like an ordinary な adjective.
