Piece of fish when the French girl comes to tea (6)
I believe the answer is:
fillet
'piece of fish' is the definition.
'fillet' can be an answer for 'piece' (fillet is a kind of piece). I am not certain of the 'of fish' bit.
'the french girl comes to tea' is the wordplay.
'the french girl' becomes 'fille' (I've seen this in another clue).
'comes to' is a charade indicator (letters next to each other).
'tea' becomes 't' (I've seen this in other clues).
'fille'+'t'='FILLET'
'when' is the link.
Can you help me to learn more?
(Other definitions for fillet that I've seen before include "Cut of steak; ribbon strip" , "round head?" , "Choice piece of boneless meat (6)" , "Thick piece of boneless meat or fish" , "Remove bones of (fish)" .)
