Neglected study may easily become (5)
I believe the answer is:
dusty
'neglected' is the definition.
Both the answer and definition are adjectives. Perhaps there's a link between them I don't understand?
'study may easily become' is the wordplay.
'study' anagrams to 'DUSTY'.
But, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for dusty that I've seen before include "Covered in fine particles" , "Needing cleaning" , "Neglected and in need of a clean" , "Miller - or answer, may be!" , "Ms Springfield" .)
