てもいい・なくてもいい・ても・なくてもかまわない・させてもらう・てもつかえないPermission and non-obligationChoose according to what is being made acceptable. てもいい allows an action; なくてもいい allows you to leave it undone. The other forms add a viewpoint: no inconvenience, permission received as a favor, or a formal judgment that there is no practical obstacle.5 pointsしかない・わけにはいかない・よりほかない・ざるをない・ないわけにはいかない・なくされるChoosing a no-alternative expressionStart by asking what the situation has eliminated. If only one practical option remains, choose an option-focused form. If duty rules an action in or out, choose the corresponding わけにはいかない pattern. For reluctant compulsion or formal reports of outside pressure, use a more formal form that makes that pressure explicit.6 pointsめ・なさい・てごらん・てはいけない・するな・てはならない・べからず・あるまじきChoosing a command or prohibitionChoose a directive by asking three things: are you telling someone to act or not to act, do you have a clear reason to control that person’s action, and is the setting conversational, instructional, formal, or deliberately literary? These forms are not simply rungs on one politeness ladder. A polite ending can still impose a firm rule, while an old-fashioned form may sound measured without being respectful.11 pointsなあでしょうだろうかなかしらじゃないものもんってばChoosing a sentence endingChoose a sentence ending by asking what you are doing with the listener: sharing an observation, telling them something, wondering aloud, pressing for agreement, defending yourself, or insisting that they listen. English translations such as “right?” and “you know” are only rough clues. Relationship, context, and spoken tone often decide the real effect.10 points
