示唆

1. Origins, structure, and basic meaning

• Structure: 示唆 is read as しさ and is a noun and suru-verb for suggesting or implying a possibility or meaning without stating it directly as fact.
• Basic usage: The implied content takes を, as in 可能性を示唆する and 交代を示唆する.

2. Common pitfalls and similar expressions

• Suggestion versus proof
  • Data that 示唆する a cause supports its possibility but does not establish that cause as proven.
• Data and remarks
  • A change in data can provide indirect evidence, while a remark can carry an implication through what it leaves unstated.
