A little store where some of us get new hats (5)
I believe the answer is:
stash
'a little store' is the definition.
'stash' can be an answer for 'store' (stash is a kind of store). I am not sure about the 'a little' bit.
'some of us get new hats' is the wordplay.
'some of' indicates the central letters (I've seen 'some' mean this).
'us' becomes 'U.S.A.' (synonyms).
'get new' indicates an anagram (get a new order of the letters).
The middle of 'usa' is 's'.
'hats' is an anagram of 'tash'.
's'+'tash'='STASH'
'where' acts as a link.
Can you help me to learn more?
(Other definitions for stash that I've seen before include "Hide in a secret place" , "collection" , "Cache" , "Consignment of drugs" , "Secret store of valuables" .)
