Not all met disaster in area of growth (9)
I believe the answer is:
allotment
'area of growth' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'not all met disaster' is the wordplay.
'disaster' indicates an anagram.
'not'+'all'+'met'='notallmet'
'notallmet' anagrammed gives 'ALLOTMENT'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for allotment that I've seen before include "Vegetable plot" , "Plot of land rented for growing vegetables" , "Rented garden plot" , "cultivated area" , "Plot of public land rented to an individual for gardening" .)
