Gathers flowers for minor suppliers (4,5)
I believe the answer is:
tuck shops
'minor suppliers' is the definition.
Although both the answer and definition are plural nouns, I can't understand how one could define the other.
'gathers flowers' is the wordplay.
'gathers' becomes 'tucks' ('tuck' can be a synonym of 'gather').
'flowers' becomes 'hops' (I can't justify this - if you can you should believe this answer much more).
'tucks'+'hops'='TUCK-SHOPS'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for tuck shops that I've seen before include "where 10 [SCHOLLBOY] s buy food" , "more than one place selling confectionery" .)
