Temperature attracting cheers in the sea in part of France (8)
I believe the answer is:
brittany
'part of france' is the definition.
('Brittany' is part of 'france')
'temperature attracting cheers in the sea' is the wordplay.
'temperature' becomes 't' (abbreviation).
'attracting cheers' becomes 'ta' (I am not sure about this - if you are sure you should believe this answer much more).
'in the' is an insertion indicator.
'sea' becomes 'briny' ('briny' can be a synonym of 'sea').
't'+'ta'='tta'
'tta' inserted into 'briny' is 'BRITTANY'.
'in' is the link.
Can you help me to learn more?
(Other definitions for brittany that I've seen before include "Region of NW France" , "Tiny brat (anag) - region of France" , "Bratty in northwestern France" , "Province of northwestern France" , "French region where Bretons come from" .)
