[JLPT grammar] intransitive verb+ている indicates the result of a change

Today I am going to share the homework correction quoted from my JLPT N4 course!
The student’s sentence is not correct. Can you find the mistake?


[Student’s sentence]





[My correction]

Huh? The light is on. I turned it off a while ago.

ついて is a te-form of つく(intransitive verb), つけて is a te-form of つける(transitive verb).

[transitive verb]ている indicates when the action is in progress or someone’s routine. On the other hand, [intransitive verb]ている indicates the result of a change.

This sentence indicates that someone turned on the light and that light is still on, so [intransitive verb]ている=ついている is used.



Tanaka-san is studying right now.

[transitive verb=勉強して]いる



The window is broken.

[intransitive verb=割れて]いる


I hope my explanation helps you. 😊
