Our land broken and lumpy (7)
I believe the answer is:
nodular
'lumpy' is the definition.
(I've seen this before)
'our land broken' is the wordplay.
'broken' is an anagram indicator.
'our'+'land'='ourland'
'ourland' with letters rearranged gives 'NODULAR'.
'and' acts as a link.
(Other definitions for nodular that I've seen before include "Lumpy" , "Like knots" , "With small swellings" , "Relating to swellings" , "Like a small swelling" .)
