Baby's basket of fish with one fish-catcher (8)
I believe the answer is:
bassinet
'baby's basket' is the definition.
'bassinet' can be an answer for 'basket' (thesaurus). I'm not certain of the 'baby's' bit.
'fish with one fish-catcher' is the wordplay.
'fish' becomes 'bassi' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' means one lot of letters go next to another.
'one fish-catcher' becomes 'net' (I've seen this before).
'bassi'+'net'='BASSINET'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for bassinet that I've seen before include "Type of cradle" , "Baby's cradle or pram" , "Wicker cradle" , "Hooded basket for a baby" .)
