よくある間違い：
Learners sometimes confuse "rationale" (noun) with "rational" (adjective). For example, *"a rationale person"* is incorrect; it should be *"a rational person"*. Another mistake is using it without an article in singular countable use; in most cases you need an article: say *"the rationale"* or *"a clear rationale"*, not just *"rationale"* alone.

よくある間違い：
Learners may use "rationale" here when "overview" or "summary" is meant. A rationale must explain the reasons or theory behind the structure, not just describe its parts. For example, *"This is the rationale of the book"* is unclear if it only lists chapters and does not explain why they are arranged that way.
