Yes, at one point in time I had one of these teachers that said not to use the word said. It was our English class my freshman year of high school was doing interviews, and I guess the concern is that it gets boring reading the word “said” a bunch of times when there are more expressive words available.
I was attending a writers conference, though, and one of the editors there said to use said. When writing dialogue tags, “said” is almost invisible to readers, while these other more flamboyant synonyms for said call attention to themselves and away from the story.
This link gives a good rundown on why banning certain words is a bad idea. Though, I still think that the banning of the word “very” seems legit.
Are there any words you had teachers ban in the classroom? How does it impact your writing today?
