Cackhanded, or the variation I read in an art show/artist review, ‘cackhandedness‘. Is that not a great word? It means a) left-handed and b) clumsy. In the review the meaning was clumsy.
If you don’t want to click on the link then I’ll tell you – ‘cack’ is dialect for excrement, from Old Norse or Middle Low German or Middle Dutch, from the the Latin cacare, to defecate. No doubt that ka-ka, or ca-ca, the infantile euphemism we use for shit, comes from the Latin.
The challenge here is how to use the word cackhanded in my everyday conversations.
