A great number intended, we hear, to get plot for growing (9)
I believe the answer is:
allotment
'plot for growing' is the definition.
'allotment' can be an answer for 'plot' (I've seen this before). I'm unsure of the 'for growing' bit.
'a great number intended we hear' is the wordplay.
'a great number' becomes 'allot' (I can't justify this - if you can you should believe this answer much more).
'intended' becomes 'meant' (to mean something is to intend it).
'we hear' shows a homophone (sound like).
'meant' sounds like 'ment'.
'allot'+'ment'='ALLOTMENT'
'to get' acts as a link.
Can you help me to learn more?
(Other definitions for allotment that I've seen before include "grant?" , "Rented piece of ground" , "Plot of land rented for growing vegetables" , "share in growing concern?" , "growing area?" .)
