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.
