No Doubt

I doubt I’m an alcoholic. This is true since it means that I don’t doubt I’m an alcoholic. The usage, common in sixteenth century English dialect and quite archaic across most of the English-speaking world, is still alive and kicking in Scotland, where “to doubt” can mean either “to doubt” or “to expect (esp. something unwelcome), suspect.” “I doubt it” can only mean “I doubt it” while “I doubt it’s true” can mean “I doubt it’s true” or “I expect that’s true.” So, I doubt I’m right, then. I doubt I’m an alcoholic.
