Perhaps someone here more worldly than myself can answer this.
You will see it written that in Scotland, 'whisky' means blended scotch and 'malt' means single malt. Predictably, they never call it scotch.
Is this really true?
It seems more likely to me that 'whisky' would mean Scottish whiskey of any kind, blend or malt, while 'malt' would only mean malt.
Who knows from personal experience?
