lost 9 letter wordl - anagram solver not helping!

[speakreveal]

Does anyone know a large subreddit for this type of question?

Was playing 9 letter wordl on hello wordl .net and had:

_ _ _ _ A _ I O _

The page reloaded when switching windows and lost it, and can't find the answer on anagram finders. I'm pretty sure it had R, E, D in somewhere as they were yellow. It had no T as it was grey in my other answers. I think I had a grey N also.

I tried an anagram solver for "RED?A?IO?" but can't see anything that fits. Would be useful if there was a site where you can input a known sequence within the word like "A?IO?"

Any ideas? Thanks.
