自体 (じたい)

• Reading: じたい
• Romaji: jitai
• Formation: Noun + 自体 (+ particle)
• Kanji breakdown: 自 (self) + 体 (body, entity)

Meaning

A dependent noun meaning 'itself' that is attached to a preceding noun to emphasize that the referent is the focus of discussion, often implying that even the fundamental entity is noteworthy or problematic.

自体 emphasizes the noun it follows by drawing attention to the very entity itself rather than its attributes or consequences. It often implies surprise or that the thing in question is more significant than expected. For instance, 計画自体に問題がある means 'There is a problem with the plan itself,' suggesting the flaw is fundamental, not peripheral. Unlike そのもの, which highlights purity of essence, 自体 tends to carry a nuance of 'even X' or 'X as such.' It frequently appears in sentences where the speaker wants to isolate the core issue. It is common in both spoken and written Japanese and pairs naturally with が, に, は, and を particles.

Examples

1. この法律自体が時代に合っていないのではないか。 Isn't this law itself out of step with the times?
2. 参加すること自体に意義があると考えている。 I believe there is significance in the act of participating itself.
3. 試験の内容自体は難しくなかったが、量が多すぎた。 The exam content itself was not difficult, but there was too much of it.
