A nice word, made all the more atractive by its unknown origin.kilter
in out of kilter (1628) variant of Eng. dial. kelter (1606) "good condition, order," of unknown origin.
I wonder if it has anything to do with kilts. Not to be overly silly, but if kilt wearers are as exposed to the breeze as reported, if they were out-of-kilt, that would be out of kilter, wouldn't it?
