Definition:
The phrase "on purpose" is an adverb that means something is done with intention or deliberately. When someone does something "on purpose," it means they meant to do it and it was not a mistake.
Simple Example:
In a Question:
Intentionally: This is a synonym for "on purpose."
Example: "He left the door open intentionally."
Deliberately: Another synonym that also means to do something with careful consideration.
Example: "She deliberately chose to study late at night."
By accident: This means something happened unintentionally.
Example: "I found the lost book by accident."
On purpose vs. by accident: This is a common contrast used in English to clarify whether an action was intentional or not.
