One group of people who are very big on the idea of precision in language are writers and literary critics. There’s a very well respected school of thought that says that good writing is in large part about selecting the right word or words - * le mot juste* - to accurately express your thoughts to the reader. Imprecision leads to misunderstanding, lack of clarity and to a greater or lesser extent, failure of communication.
See for example, Twain on Fennimore Cooper, giving both an explanation of the problem and some examples:
Cooper’s word-sense was singularly dull. When a person has a poor ear for music he will flat and sharp right along without knowing it. He keeps near the tune, but it is not the tune. When a person has a poor ear for words, the result is a literary flatting and sharping; you perceive what he is intending to say, but you also perceive that he doesn’t say it. This is Cooper. He was not a word-musician. His ear was satisfied with the approximate word. I will furnish some circumstantial evidence in support of this charge. My instances are gathered from half a dozen pages of the tale called Deerslayer.
He uses “verbal,” for “oral”; “precision,” for “facility”; “phenomena,” for “marvels”; “necessary,” for “predetermined”; “unsophisticated,” for “primitive”; “preparation,” for “expectancy”; “rebuked,” for “subdued”; “dependent on,” for “resulting from”; “fact,” for “condition”; “fact,” for “conjecture”; “precaution,” for “caution”; “explain,” for “determine”; “mortified,” for “disappointed”; “meretricious,” for “factitious”; “materially,” for “considerably”; “decreasing,” for “deepening”; “increasing,” for “disappearing”; “embedded,” for “enclosed”; “treacherous;” for “hostile”; “stood,” for “stooped”; “softened,” for “replaced”; “rejoined,” for “remarked”; “situation,” for “condition”; “different,” for “differing”; “insensible,” for “unsentient”; “brevity,” for “celerity”; “distrusted,” for “suspicious”; “mental imbecility,” for “imbecility”; “eyes,” for “sight”; “counteracting,” for “opposing”; “funeral obsequies,” for “obsequies.”
In the modern era, Dan Brown has also been sharply criticised for his word choice (alongside his sentence structure, use of metaphor, lack of detail, excess of detail and a dozen other literary sins, none of which have been an obstacle to his considerable success).*
I bring this up because the other great tradition of writing and literary criticism is being a complete dick to other writers, as can well be seen from the Twain essay. And I am prepared to bet quite a lot of money that on Reddit forums for aspiring writers there is much unpleasantry produced about aspiring new author’s word choice for all the reasons given above - except that without excusing the nastiness, underneath it is what might genuinely be valid criticism, in that unlike bakery what words people are using really is the point.
