I've been trying to work out the parsing of this for the best part of an hour and I've just about reached breaking point!
5d - Evergreen singer almost entirely ignored in awards (7)
My answer is a synonym for "awards" (as a verb) from an 8 letter "evergreen" minus "I".
I'm pretty sure there's also an extra "I" (unless that's the "I" from "evergreen") generated by the wordplay but am at a loss as to understand how that results from "singer almost entirely ignored" which makes me wonder if I've got it all wrong.
