Already to talk about things that happened before now or happened sooner than expected, e.g. Wheres Tom? Hes already gone home. We put already between have/has and the past participle. They are always affirmative.

Yet in negative sentences to say that something has not happened up to the present time, e.g. He hasnt arrived yet.
