A send does allow you to determine how much of the input signal to send without effecting the amount of signal to the track or bus output.
So it is quite correct to say that you are taking some of the signal. "Some" could be anywhere from none to all of the input signal depending on the send level you set. So while it's a copy of the input signal you determine the level.
Thank you Mudgel I agree with you completely on this but the words I used were meant to give a visualization of the idea more than being totally accurate. I believe it was accurate as well. My first inclination was to use "tap into" instead of "take some" but I thought even though that is more accurate it might be confusing to the OP. So "take some" may be construed inaccurately it is as you point out very descriptive.
I have often used the take some phrase in order to get the concept across. No one up till now has found fault with it. In any case its good that it is well clarified now.
