Fish one gets to catch in a wicker container (8)
I believe the answer is:
bassinet
'container' is the definition.
(bassinet is a kind of container)
'fish one gets to catch in a wicker' is the wordplay.
'fish' becomes 'bass' (bass is a kind of fish).
'one' becomes 'I' (Roman numeral).
'gets' says to put letters next to each other.
'to catch in a wicker' becomes 'net' (I can't explain this - if you can you should believe this answer much more).
'bass'+'i'+'net'='BASSINET'
Can you help me to learn more?
(Other definitions for bassinet that I've seen before include "Hooded basket for a baby" , "Baby's cradle or pram" , "Wicker cradle" , "Type of cradle" .)
