Introduction
In this response, we will discuss the sentence "He has done it on purpose" in terms of passive voice and English grammar basics. We will explain the concept of passive voice and provide a detailed analysis of the sentence structure.

Passive Voice
The passive voice is a grammatical construction where the subject of a sentence receives the action of the verb, rather than performing the action. In passive voice sentences, the object of the active voice sentence becomes the subject, and the subject of the active voice sentence may be omitted or introduced with a preposition.

Sentence Analysis
The sentence "He has done it on purpose" is in the active voice, where "he" is the subject, "has done" is the verb phrase, and "it" is the object. However, the sentence does not contain a passive construction. Instead, it uses an active construction with the verb "do" in the present perfect tense.

Meaning of the Sentence
The sentence means that the person referred to as "he" intentionally performed the action mentioned by the verb "do." The exact action is not specified in the given sentence, but it is implied that it was done deliberately.

Key Points:
- The sentence is in the active voice, not passive.
- The subject "he" is performing the action.
- The verb phrase "has done" indicates that the action was completed in the past and has relevance to the present.
- The phrase "on purpose" clarifies that the action was intentional and not accidental.

Conclusion
In summary, the sentence "He has done it on purpose" is not an example of passive voice. It is in the active voice and conveys that the person referred to as "he" deliberately performed the action. Understanding the difference between active and passive voice is essential for effective communication and grammatical accuracy.
