Name European plant in allotment (10)
I believe the answer is:
allocation
'allotment' is the definition.
(synonyms)
'name european plant' is the wordplay.
'name' becomes 'Al'.
'european plant' becomes 'location' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'al'+'location'='ALLOCATION'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for allocation that I've seen before include "Distribution, assignment" , "budget" , "Share" , "Allotment" , "Apportionment" .)
