Amenazar (Spanish for “to threaten”) has a curious origin: from the Latin mine, meaning, “lead” or sometimes “silver.” Remember, this was the material that weapons — swords, arrowheads, etc — were made of. If you don’t comply with my threat–I will hurt you!
Although this isn’t directly related to the English mine (the place where you get silver!), they might have the same original root–and it is an easy mnemonic. After all, we mine silver in the mines.
