Elsewhat: Something else.
Once a respectable English word, deriving from Old English /elles hwat/. Unfortunately it died out.
It takes time and effort which might usefully be spent doing elsewhat.(The Face, Nick Logan)
His mind was on elsewhat that hot summer evening after tea. (Memories of the Gorbals)
But his eyes were saying elsewhat (One shining summer, Quinn Wilder)
And you thought I just made the word up; shame on you
