Gustave Flaubert famously coined the term mot juste. The idea of finding the right word and avoiding synonyms to vary the language was famously seized upon by Ernest Hemingway in his autobiographic tale of boozing and writing in Paris, A Moveable Feast.
I always appreciated the idea and tended in that direction but have come to wonder if it is more so mot paresseux (lazy), just sticking in the word out of habit, rather than some kind of idealization. I still prefer the idea to Mot SAT, but it’s something to consider.
