Re: Can you raise only one eyebrow?
That's odd, isn't it? That ambidextrous has no simple word for the opposite.
I propose Unichiral for single-handedness. For right handedness, just plain simple "Dextral" (from dexter, Latin for right) and "Sinistral" for left handedness, from the latin Sinister for left.
Single, right and left handed ARE simple words. Ambidextrous is not.
They couldn't hit an elephant at this distance.
