See chook smile in opera? (9)
I believe the answer is:
lohengrin
'opera?' is the definition.
(I've seen this before)
'see chook smile' is the wordplay.
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'chook' becomes 'hen' (I can't explain this - if you can you should believe this answer much more).
'smile' becomes 'grin' (synonyms).
'lo'+'hen'+'grin'='LOHENGRIN'
'in' is the link.
Can you help me to learn more?
(Other definitions for lohengrin that I've seen before include "Wagnerian opera" , "Musical entertainment" , "Wagner opera" .)
