Hear about the Italian bishop in narrow-brimmed headgear (6)
I believe the answer is:
trilby
'headgear' is the definition.
(trilby is a kind of headgear)
'hear about the italian bishop in' is the wordplay.
'hear' becomes 'try' (to hear or try a case in the legal sense).
'about' means one lot of letters goes inside another.
'the italian' becomes 'il' ('the' in Italian).
'bishop' becomes 'B' (chess abbreviation).
'in' means one lot of letters goes inside another.
'try' placed around 'il' is 'trily'.
'trily' enclosing 'b' is 'TRILBY'.
'narrow-brimmed' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for trilby that I've seen before include "A man's hat or novel by du Maurier" , "Indented felt hat" , "Sinatra's hat?" , "Hat named after fictional character" , "Type of hat" .)
