Quiet pixie getting some storage (5)
I believe the answer is:
shelf
'some storage' is the definition.
(thesaurus)
'quiet pixie getting' is the wordplay.
'quiet' becomes 'sh' ('sh' is used to tell someone to be quiet).
'pixie' becomes 'elf' (synonyms).
'getting' says to put letters next to each other.
'sh'+'elf'='SHELF'
(Other definitions for shelf that I've seen before include "display" , "board" , "Storage ledge" , "Ledge for books etc" , "Rock ledge; underwater bank" .)
