  The word 'ինչ' is used as an interrogative pronoun to ask a question about an action or object.

• Ես չեմ հասկանա, թե ինչու դա արեց։

  The word 'ինչու' is derived from 'ինչ' and is used to ask questions concerning reasons or causes.

  Here, 'ինչ' is acting as a content interrogative to introduce the nature of a subject in indirect speech.
