You just picked it up because you want a better word than the first word that came to mind, the simplest and most obvious word.
Maybe the obvious word isn’t sufficiently fine, and you seek a preferable substitute. Maybe you don’t want to repeat the obvious word — you think it’s more fitting to use two different terms for the same thing, one of which is superior. Maybe you want to echo a phrase or idea, but in a worthier, surpassing way.
You want your writing to be better, and you’re prepared to make it better, one better word at a time.
A good idea, you think, a laudable aim, a truly meritorious aspiration.
But a better word here and there won’t make your writing suck less. It just shows that you own a thesaurus, and don’t know when to not use it.
Better to just stop writing. Better for everyone.
