AD&D 2nd edition had a key number for each character called “To Hit Armor Class Zero”, abbreviated “THAC0”. Back when this was the current edition, my friends and I argued over whether it should be pronounced thake-oh or thack-oh (whether the ‘A’ in the middle should be short or long), or maybe we were both wrong and it should be some other way.
Was there ever any official guidance from TSR, Wizards of the Coast, D&D creators, or some other official source as to how to pronounce this key term? Or does each playgroup just do their own thing?
