Lock of hair, very French, extended at end? (5)
I believe the answer is:
tress
'lock of hair' is the definition.
(I've seen this before)
'very french extended at end?' is the wordplay.
'very french' becomes 'tres' ('very' translated into French).
'extended at end?' becomes 's' (I can't justify this - if you can you should believe this answer much more).
'tres'+'s'='TRESS'
Can you help me to learn more?
(Other definitions for tress that I've seen before include "Long lock or plait of hair" , "is a bit of a shock" , "Obsolete support" , "Bit of hair" , "Switch" .)
