On reusing words
One of the rules I was taught for writing, but never really respected, was not to reuse words: if you have to use it a second time, use a synonym. Eventually I realized what the real rule is. It’s okay to use the same word for the same thing. What is bad is to use the same word for a different thing. Even if the word would be a good fit for that second thing, if it’s already in use you should choose another, because otherwise readers will conflate the two.
