HSK 2 grammar · adverb
故意
故意 — on purpose / deliberately
Pattern
+ +
( ) can be left out · other words may come before, between and after
How it works
故意 before a verb says the action was done on purpose, not by accident. It goes after the subject and before the verb.
Examples
他故意不告诉我。
Tā gùyì bú gàosu wǒ.
He deliberately didn't tell me.
对不起,我不是故意的。
Duìbuqǐ, wǒ bú shì gùyì de.
Sorry, I didn't do it on purpose.
你是故意的吗?

Did you do that on purpose?
