Revolutionary court decision's beginning significant growth (7)
I believe the answer is:
redwood
'significant growth' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'revolutionary court decision's beginning' is the wordplay.
'revolutionary' becomes 'red'.
'court' becomes 'woo' (synonyms).
'beginning' indicates taking the first letters.
The initial letter of 'decisions' is 'd'.
'red'+'woo'+'d'='REDWOOD'
Can you help me to learn more?
(Other definitions for redwood that I've seen before include "Californian conifer" , "may be growing in California" , "Giant North American conifer" , "Giant American tree" , "Giant California conifer" .)
