Lesson 132: ことに なって いる・ことに して いる・〜こと

N3 · Lesson 132 · 18 min — Rules, habits, notices: two signs under the tree

Last lesson, Rin said 「春はるに 会あえますように」 at the shrine. You already know ことに する (you decide) and ことに なる (it gets decided). In this lesson, adding いる makes them "rule" and "habit". Then you'll learn 〜こと on notices. Start with the comic!

After this lesson, you can:

Two Signs Under the Tree

After making a wish at the shrine, Rin goes back to the old tree across from くまや. (保存樹ほぞんじゅ = protected old tree, 決きまり = rule)

ことに なって いる = a rule, ことに して いる = your own habit, 〜こと = an instruction on a notice. This old cherry tree has no 「保存樹ほぞんじゅ」 sign. In other words, there is no rule against cutting it... Next lesson: what if this tree disappears?

Words for this lesson: rules and habits

Grammar 1 / 3: ことになっている

Dictionary form / ない form+ことに なって いる = "it is the rule that ~ / it is arranged that ~". You did not decide it. A school, company or ward office set the rule or arrangement, and it is still in effect now.

Grammar 2 / 3: ことにしている

Dictionary form / ない form+ことに して いる = "I always ~ / I make it a rule to ~". It is a habit or principle you decided on yourself and keep doing.

Grammar 3 / 3: 〜こと (rules)

Dictionary form / ない form+こと。= "must ~" / "must not ~". It is an instruction written on notices, rules and homework sheets. The sentence ends right at こと.
