Can someone explain: evt.target

I am trying to read some tutorials on the Delegate class and EventDispatcher class. I keep seeing the term “evt.target” and figure it is meaning something like someEvent.targetThatProducedTheEvent? or maybe someEvent.targetToNotifyAboutTheEvent? I would love it someone could take the time to really explain these classes to me. I haven’t been able to find a tutorial geared towards newbies to the classes. Thanks
