You Can’t Have That

If there had been a first word,
A first well-formed blurt or wave
Made to mean and hold its shape,

A word you would know as one,
Would class as such by its use,
With what it meant known or not,

That word’s long lost to air now,
Can’t be caught and won’t come back.
No way you can bring it back.

We give these words to that gap
That can’t be filled, to the word
That first took flight from the past.
