Improper Usage
Avoid using "とおりだ" for situations where logical reasoning (rather than strict similarity) is the focus, as this can sound confusing or unnatural. Similarly, using "どうりだ" in cases where similarity rather than logic is emphasized can sound out of place.
Key Points to Remember
- "とおりだ" and "とおりに" emphasize that something happens in the same way or exactly as described, planned, or expected.
- "どうりだ" and "どうりに" convey logical consistency or sensibility, helping explain why something happened.
- Choose "とおり" to show alignment with instructions, assumptions, or external references, while "どうり" highlights understanding, reasoning, or common sense.
Formality
Both "とおり" and "どうり" expressions are neutral and can be used in both formal and informal contexts. However, "どうりだ" is slightly more conversational and may not be suitable for highly formal written contexts without modification.
