What is the difference between kowareru and kowasu?

The Basics: “Kowareru” vs “Kowasu”

What Does “Kowareru” Mean?

Kowareru (壊れる) is a verb that means “to break” or “to get broken.” It is an intransitive verb, which means the subject of the sentence undergoes the action. In other words, something breaks by itself, or the focus is on the state of being broken rather than who or what caused the action.

What Does “Kowasu” Mean?

Kowasu (壊す) also means “to break,” but it is a transitive verb. This means that it requires a direct object and refers to someone or something actively causing the breakage. The emphasis here is on the person or agent performing the action.

Key Grammatical Differences

Transitive vs Intransitive Verbs in Japanese

Japanese frequently uses pairs of transitive and intransitive verbs to indicate who is performing an action versus when an action happens on its own.

• Kowareru (壊れる) – Intransitive: The subject gets broken.
• Kowasu (壊す) – Transitive: Someone breaks the subject.

Understanding this distinction is essential for constructing accurate sentences and avoiding confusion.

Example Sentences

Using “Kowareru” in Sentences

• 時計が壊れた。
  The clock broke. (The clock broke by itself or the cause is unknown.)
• このおもちゃはすぐ壊れます。
  This toy breaks easily.

Notice that there is no agent in these sentences; the item itself is the focus.

Using “Kowasu” in Sentences

• 私は時計を壊した。
  I broke the clock. (The speaker is actively performing the action.)
• 子供がおもちゃを壊しました。
  The child broke the toy.

Here, the person doing the breaking is clearly identified.

Common Mistakes and How to Avoid Them

One of the most common errors for Japanese learners is mixing up transitive and intransitive verbs. Remember:

• Use kowareru when something breaks on its own or you do not want to specify the agent.
• Use kowasu when someone or something intentionally breaks something else.

Practicing with example sentences and listening to native usage—such as through language exchange apps or AI-powered tools like Talkpal—can help reinforce these patterns.

Tips for Mastering These Verbs

• Memorize verb pairs: Japanese often has many such pairs (e.g., aku – to open (intransitive) vs akeru – to open (transitive)). Recognizing patterns helps with comprehension and production.
• Practice both forms: Make your own sentences using both “kowareru” and “kowasu” to solidify the difference.
• Listen and repeat: Listen to native speakers, such as in dramas, anime, or audio provided by platforms like Talkpal, and repeat sentences to internalize correct usage.

Conclusion

Differentiating between “kowareru” and “kowasu” is a fundamental part of mastering Japanese verbs. The key takeaway is that “kowareru” is used when something breaks on its own (intransitive), while “kowasu” is used when someone intentionally breaks something (transitive). By practicing these verbs in context and leveraging modern language learning tools, you’ll become more comfortable and accurate in your Japanese communication.
