Gather in rushes around five tons (7)
I believe the answer is:
harvest
'gather in' is the definition.
(I've seen this before)
'rushes around five tons' is the wordplay.
'rushes' becomes 'hares' (I am not sure about this - if you are sure you should believe this answer much more).
'around' indicates putting letters inside.
'five' becomes 'V' (Roman numeral).
'tons' becomes 't'.
'hares' going around 'v' is 'harves'.
'harves'+'t'='HARVEST'
Can you help me to learn more?
(Other definitions for harvest that I've seen before include "reap rewards" , "Time to gather the crops" , "Cut down" , "seasonal collection" , "Process of gathering mature crops" .)
