Former union leader about to get grazing land (7)
I believe the answer is:
pasture
'grazing land' is the definition.
(synonyms)
'former union leader about' is the wordplay.
'former' becomes 'past' (similar in meaning).
'union leader' becomes 'u' (I can't explain this - if you can you should believe this answer much more).
'about' becomes 're' ('re' means regarding or about).
'past'+'u'+'re'='PASTURE'
'to get' is the link.
Can you help me to learn more?
(Other definitions for pasture that I've seen before include "Meadow" , "Land suitable for grazing" , "Grassland" , "Meadowland" , "Land for grazing cattle" .)
