Am pretty new to Julia, I guess this has been discussed before. Anyway…

In the [Julia documentation](https://docs.julialang.org/en/v1.7-dev/base/collections/#Dequeues) there’s a heading Dequeues. I gather this is a variant spelling of Deques, both pronounced _decks_. Isn’t that needlessly confusing? Dequeue is also a verb, _de-kew_, in this field, while Deque _deck_ is not, plus I’m not sure it makes any sense to pronounce ‘Dequeues’ as _decks_. (Maybe it all makes sense if you pronounce both nouns _de-kew_.)

I looked at [the wikipedia page](https://en.wikipedia.org/wiki/Double-ended_queue), which says the ‘dequeues’ spelling is deprecated, although some libraries and a couple of books use it.

Is there any (good) reason changing the spelling to Deques wouldn’t be better? Thanks.

As a non-native english speaker Deque is not immediately clearer. I would need to check de precise difinition for both of the cases. If it is an abbreviation, why not explicitly writting “Double-ended queues”? Anyway I suppose you can open a pull request to the documentation repository and It can be discussed in there!

In DataStructures.jl, it is `Deque`:
