Identify the error: She has wrote a letter.

The correct answer is wrote because the perfect aspect requires a past participle verb form rather than a simple past tense form.

• Step 1 (Grammatical Structure): The present perfect tense is formed by combining the auxiliary verb 'has/have' with the past participle (V3) form of the main verb.


• Step 2 (Correction): The simple past of 'write' is 'wrote', but its past participle is 'written'. The correct phrase should read: 'She has written a letter.'


• Incorrect Options:
  
  
  
  • has is incorrect because it is the appropriate singular helping verb to pair with the third-person singular subject 'She'.
  
  
  • a letter is incorrect because it acts as a grammatically sound direct object to receive the action.
  
  
  • No error is incorrect because using a simple past verb with a perfect helper is an explicit grammatical flaw.
