Wet rubbish? Female in the morning collects a great deal (7)
I believe the answer is:
flotsam
'wet rubbish?' is the definition.
(flotsam is sea wreckage)
'female in the morning collects a great deal' is the wordplay.
'female' becomes 'f' (common abbreviation).
'in the morning' becomes 'am'.
'collects' indicates putting letters inside.
'a great deal' becomes 'lots' (I've seen this before).
'f'+'am'='fam'
'fam' placed around 'lots' is 'FLOTSAM'.
(Other definitions for flotsam that I've seen before include "Wreck" , "Vagrants" , "Things going adrift" , "Shipwreck goods floating" , "Wreckage adrift at sea" .)
