Star joins the French politician to get source of UV (7)
I believe the answer is:
sunlamp
'get source of uv' is the definition.
I can't judge whether this definition defines the answer.
'star joins the french politician' is the wordplay.
'star' becomes 'sun' (the Sun is a star).
'joins' is a charade indicator (letters next to each other).
'the french' becomes 'la' (one of the French words for 'the').
'politician' becomes 'MP' (Member of Parliament).
'sun'+'la'+'mp'='SUNLAMP'
'to' is the link.
Can you help me to learn more?
(Other definitions for sunlamp that I've seen before include "Source of UV rays for cosmetic purposes" , "Tanner" , "Device used in artificial tanning" .)
