I once was part of a writing group that excoriated me for the following line, "She was grabbed by a tentacle from the murky depths below." They said it was redundant, and I said it was poetic.
- murky: hidden
- depths: unknown
- below: beneath her
I pointed out that poetry was often redundant to really convey a point, and I felt my line captured the mood I was looking for: a kind of deep-sea horror. They said it was better said, "She was grabbed by a tentacle from the depths," but that that sounded too formal, like "the Depths" was an apartment complex (with access to pools and a tennis court, see our ad in the Journal, "The Depths at Kensignton: Our Homes are Your Values"). "The depths are below by default," said another writer. "And everyone knows sea water is murky."
I would like to point out that none of them ever got published. So nyahh!
