I am owned by every man, though my length differs. Their wives use me after getting married. What am I?
I am rarely touched but often held and if you are smart you'll use me well.
My voice is tender my waist is slender and I'm often invited to play. Yet wherever I go I must take my bow or else I have nothing to say.
My first though water cures no thirst my next alone has soul and when he lives upon my first he then is called my whole.
I repeat only the last word you say. The more I repeat, the softer I got. I cannot be seen but can be heard. What am I?
