“Imagine, for example, that the gods decided to bestow upon Sisyphus a modicum of mercy. The rock, the hill, the never-ending, pointless labor all remained nonnegotiable as far as the gods were concerned, but the mercy of the gods was to change Sisyphus’s attitude to these things. … He is never happier than when rolling large boulders up steep hills, and the gods have offered him the eternal fulfillment of this strange desire.” — Mark Rowlands, The Word of Dog: What Our Canine Companions Can Teach Us About Living a Good Life, 2024

It wouldn’t be wrong to say that the English language has more than a modicum of words referring to a small amount of something—it has oodles, from smidgen to soupçon. But while modicum can be applied to countable or physical things (like words or salt) it is almost always applied instead to abstract concepts like respect, success, control, hope, dignity, or privacy. Modicum traces back to the Latin noun modus, meaning “measure,” which just so happens to be the ancestor of more than a modicum of English words, from moderate and modify to mold and commode.
