Thanks! And funny, I was kinda-weirdly thinking about you, the other day.
And no, I don't come with crude-pitchforks, like some might.
So... it began with the idea of Brits changing up the meaning / pronunciation of "two pence" in to "tuppence," over time. That is-- the "oo" vowel changing in to an "uh" sound, over time.
It's... some real work to understand, especially going by a blockhead such as myself. Eh, over & out, mssr. Over & out.
