I think you'll find, RM, that
decluttered has 11 letters, which pretty much rules it out for the puzzle, as presently designed.
Declutter, however, does seem as if it should be allowed. I can't see it in any dictionary, but it is certainly in frequent use in magazines, newspapers and books. The hyphenated form
de-clutter is also used, but it appears the unhyphenated spelling is at least as common.
So I will add this word, N-A.
For those like Birdy who feel they are falling behind in the decluttering stakes, an interesting book is
A Perfect Mess, by Eric Abrahamson and David H. Freedman. The book claims that a lot of the efforts put into tidiness are misguided. It argues that sometimes the time spent on creating and maintaining perfect order is a lot less than the time saved. The authors also suggest that an apparently messy desk may have its own, spontaneously generated, order - with the items that have been used recently near the top of a pile of papers, documents relevant to a common task tending to be together, etc. If you're interested, got to the website and read some of the extracts from the book.
