A tool, device, or person that flattens something; anything used to make something flat or level.
From 'flatten' (verb) + agent suffix '-er'. Describes both mechanical devices like rollers and figuratively people or things that reduce or diminish.
A 'flattener' could be a steamroller literally flattening asphalt, a rolling pin flattening dough, or even a 'flattener' as in a knockout punch—the word's flexibility shows how English loves reusing the same pattern for new meanings!
