Don't get me started on kilometre with the stress on the second syllable. Nobody pronounces millimetre or centimetre like that. I wonder if there is confusion with words ending in meter in the sense of measure, like odometer, speedometer, etc. Or a throwback to gasometers?
I hadn't thought about the stress on a syllable containing a double letter before, but mistress and related words (temptress, seamstress, etc.) seem to disprove the rule rather as windlass does.
Talking of which, according to my SOD there are two different meanings for windlass with two different derivations, but I'll stop here.
Except to suggest, Gracesmum, that Brecht himself tended to abandon his Verfremdungseffekt in his best works, which are often the better for it.
