Has is a form of the verb to have. Has she fed the dog? Has he done his chores? It is a conjugation of the verb that is pertinent to only the third person singular (he, she, it). It is present tense of the verb example: "Have they done this?" "Has she done that?"This past tense asks if something has been done prior to, or as my spanish teacher says past in the future. When you ask if something has already been done, it is uncertain if it has been done but it could have been. "she has done it" it has already been done in the past. I think it's called a helping verb.
