Reduced growth of fruit at end of orchard (6)
I believe the answer is:
pruned
'reduced growth' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Maybe they are linked in a way I don't understand?
'fruit at end of orchard' is the wordplay.
'fruit' becomes 'prune' (prune is a kind of fruit).
'at end of' says to take the final letters.
The last letter of 'orchard' is 'd'.
'prune'+'d'='PRUNED'
'of' is the link.
Can you help me to learn more?
(Other definitions for pruned that I've seen before include "Cut away overgrown branches" , "Trimmed shrubs etc to promote growth" , "(Of a shrub) cut back" , "reduced to a minimum?" , "Cut back, cropped" .)
