厄年

1. Origins, structure, and basic meaning

• Structure: 厄年 is read as やくどし and is a noun for an age-year traditionally regarded as requiring special caution because of possible misfortune.
• Basic usage: Use 今年が厄年だ for the applicable year and 厄年の習わし for customs associated with it.

2. Common pitfalls and similar expressions

• Traditional belief
  • It is a cultural belief and custom tied to age, not an objective prediction that misfortune must occur.
• Customs vary by context
  • Who is considered to be in an unlucky year and what practices follow depend on tradition and region, so the word alone does not establish every detail.
