  • 了解りょうかいJLPT N1approx.Common

  • 合意ごういJLPT N1approx.Common
    noun, suru verb, intransitive verbConsent as mutual agreement or accord reached between parties. Use this when two or more sides come to a shared decision, as in agreement after negotiation, rather than one person's individual acceptance.
