Pro Tip
Passive vs. Active
決まる is the passive form of 決める. Use 決まる to describe the result of a decision (e.g., 試合に日程が決まった), and 決める to describe the act of deciding (e.g., 私は日程を決めた).
Gold Rule
Natural State
決まる often describes something that naturally or inevitably happens, not just a human decision. For example, この服は君に決まってる means 'This outfit naturally suits you,' not 'I decided this outfit for you.'
Word Origin
From the verb 決める (kimeru, 'to decide') + まる (maru, a verb suffix indicating completion or natural state). The passive form 決まる emphasizes the result of a decision being settled.
Usage Notes
決まる is intransitive and describes the state of something being decided or fixed. It is often used with に to indicate the result of the decision (e.g., 来週に決まる).
