Uneven, like a plot of land? (6)
I believe the answer is:
patchy
'uneven' is the definition.
(similar in meaning)
'a plot of land?' is the wordplay.
'a plot' becomes 'patch' ('patch' can be a synonym of 'plot').
'of land?' becomes 'y' (I can't explain this - if you can you should believe this answer much more).
'patch'+'y'='PATCHY'
'like' is the link.
Can you help me to learn more?
(Other definitions for patchy that I've seen before include "Uneven in quality - mended too often" , "Often repaired" , "Irregular or uneven" , "Irregular in quality" , "Uneven in quality; showing signs of repair" .)
