Where did the name Horseradish come from?!
Answers: A horseradish
More recent appreciation of horseradish is believed to have originated in Central Europe, the area also linked to the most widely held theory of how horseradish was named. In German, it?s called "meerrettich" (sea radish) because it grows by the sea. Many believe the English mispronounced the German word "meer" and began calling it "mareradish." Eventually it became known as horseradish. The word "horse" (as applied in "horseradish") is believed to denote large size and coarseness. "Radish" comes from the Latin radix meaning root.

Horseradish is a perennial plant of the Brassicaceae family, which includes mustard and cabbages. The plant is probably native to southeastern Europe and western Asia, but is popular around the world today. It grows up to 1.5 metres (five feet) tall and is mainly cultivated for its large white, tapering root.
The horseradish root itself has hardly any aroma. When cut or grated, however, enzymes from the damaged plant cells break down sinigrin (a glucosinolate) to produce allyl isothiocyanate (mustard oil), which irritates the sinuses and eyes. Once grated, if not used immediately or mixed in vinegar, the root darkens and loses its pungency and becomes unpleasantly bitter when exposed to air and heat.
Hope this helps.
