How do I change the contents of a string when I click on an image?

Question

I have hundreds of images that need to play a unique sound when clicked.  In order to simplify the building of this flash file I need to streamline it in a way that will allow me to change only one word.  Below is some example code.  I think the reason it doesnt work is that I am declaring "word" twice...any suggestions anybody?  Thanks in advance...
import flash.events.MouseEvent;
stop()
var word:String = "family"
trace (word + "_nv")
this[word+ "_nv"].addEventListener(MouseEvent.CLICK, playaudio);
this[word+"_nv"].buttonMode = true;
var word:String = "grandchildren"
trace (word + "_nv")
this[word+ "_nv"].addEventListener(MouseEvent.CLICK, playaudio);
this[word+ "_nv"].buttonMode = true;
function playaudio (event:MouseEvent):void{
this[word+"_nv"].play()

I don't see where what you show is streamlining anything.  It would save code to just use the strings instead of assigning the string to variables and using the variables.  In any case. yes, you do not want to declare the same variable twice (use "var" only once).  And your playaudio function will only work with whatever the last value of "word" that you assign.
To streamline the code you could name each mc using a numeric increment (mc_1, mc_2, mc_3, etc), and then assign your listener in just a few lines using a loop.  In the play audio function you could use the instance name of the event.currentTarget...
this[event.currentTarget.name].play();
or even
MovieClip(event.currentTarget).play();
