Category: Intentions & Decisions
The grammar pattern "V（辞書形／ない形）＋ことになっている" is used to express a rule, custom, or appointment that has been decided by an external authority or group. It focuses on the resulting state of the decision rather than the act of deciding. This pattern is often used to describe a situation where a rule or regulation has been established, and it is expected to be followed. The use of "ことになっている" emphasizes the fact that the decision has been made and is now in effect.
