Raise again in a plot in the garden (5)
I believe the answer is:
breed
'raise' is the definition.
(I've seen this in another clue)
'again in a plot in the garden' is the wordplay.
I cannot quite see how this works, but
'again' could be 're' (prefix meaning 'again') and 're' is found within the answer.
'plot' could be 'bed' (a plot of land) and 'bed' is found in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for breed that I've seen before include "Special lineage" , "Special variety within a species" , "Produce young" , "Lead to (success); kind" , "train" .)
