Joe Gould speaks of his childhood:
“Usually, when I was supposed to be paying attention to something, I was busy blowing my nose. Also, I was just generally inept. Not long ago, looking up something in the unabridged dictionary, I came across a word that sums up the way I was then, and for that matter, the way I am now — ‘ambisinistrous,’ or left-handed in both hands.”It’s for real. Webster’s Second (perhaps the unabridged dictionary Gould used?) has it, coupled with the adjective ambisinister : “Left-handed, or clumsy, in the use of both hands.” Both ambisinister and ambisinistrous are missing from the Third .
