The English adverb 'deliberately' means doing something on purpose, with intention, often after careful thought. In Japanese, this concept is expressed through various adverbs, verb forms, and phrases that convey intentionality, carefulness, or purposefulness. The most common equivalent is わざと (wazato) for everyday intentional actions, but other options exist for formal, written, or nuanced contexts.
Express that an action was done intentionally, not by accident, often with a nuance of doing something one knows is wrong or unexpected.
The most common and versatile adverb for 'deliberately' in casual and neutral speech. It often implies the action was done knowingly, sometimes with a negative or mischievous connotation.
He deliberately ignored me.
I didn't do it on purpose.

Use only when the action involves extra effort or trouble. Not for simple intentionality.
Express that an action is done slowly and with careful thought, emphasizing the manner rather than just the intentionality.
Means 'carefully' or 'cautiously'. It captures the 'deliberate' sense of taking one's time and being mindful.

Means 'elaborately' or 'with great care', often used for preparations or work done meticulously.

Literally 'on top of knowing', meaning 'knowingly' or 'with full knowledge'. Common in formal apologies or accusations.

A more casual way to say 'knowingly'. Often used in spoken Japanese to accuse someone of doing something they knew was wrong.
You did it deliberately, didn't you?
わざと is the most common and casual, often implying a bit of mischief or knowing wrongness. 故意に is formal and used in legal contexts, focusing on the act being intentional. 意図的に is neutral and simply states that there was an intention behind the action.

He deliberately destroyed the evidence.
He deliberately leaked the information.
