A Complete Guide: つまらない and くだらない
Have you heard about つまらない and くだらない? They sound pretty close, however, they are absolutely different from each other for natives. There are some cases that we feel つまらない about something, but it is not くだらない in our daily life. Let me introduce what the difference between つまらない and くだらない are today.
Uninteresting / Boring / Snooze
つまらない is used as the meaning that someone doesn’t want to do something anymore because that is uninteresting, boring or snooze for him/her. However, it does not mean nonsense, stupid, worthless and silly such as くだらない.
Worthless / Nonsense / Stupid / Silly
くだらない means “worthless / nonsense / stupid / silly “. So,くだらない is the much stronger meaning than つまらない. If someone feels something boring, he/she could use つまらない and furthermore if someone feels something boring+worthless, he/she could use くだらない. So, つまらない is not worthless rather it may be worth. However, someone is just uninteresting.
