Meaning and Usage
"同意" (どうい) means "agreement" or "consent" and is used when people share the same opinion or approve something formally or informally. It is a noun but often appears in verbal expressions like "同意する" (to agree).
Common Contexts
You will see "同意" in legal, business, and everyday conversations where approval or consent is necessary. For example, agreeing to contracts, proposals, or group decisions.
Collocations and Patterns
- 同意する: to agree or consent
- 同意を得る: to obtain consent
- 同意しない: to disagree or not consent
These patterns are useful for expressing agreement or disagreement clearly.
Register and Nuance
"同意" is neutral and can be used in both formal and informal contexts, but it often appears in more formal or official situations compared to casual words like "いいよ" or "わかった".
Common Mistake
Learners sometimes confuse "同意" with "承認" (しょうにん), which also means approval but is more formal and often used for official authorization. Use "同意" when focusing on mutual agreement or consent.
