Obtund is derived from the Latin "obtundere" (meaning to beat down or dull), which is composed of "ob-" (meaning against) and "tundere" (meaning to beat). The word "obtund" means to dull or lessen the intensity of something, often in a figurative sense.
Think of 'beating down' ('tundere') something 'against' ('ob-') to make it less sharp or intense — that's why obtund means to dull.
