Value in warmth and love comes to republic (4)
I believe the answer is:
togo
'to republic' is the definition.
(Togo is a republic in Africa)
'value in warmth and love' is the wordplay.
'value in warmth' becomes 'tog' (a blanket's warmth is measured in togs).
'and' means one lot of letters go next to another.
'love' becomes 'o' (love means zero in tennis).
'tog'+'o'='TOGO'
'comes' acts as a link.
(Other definitions for togo that I've seen before include "W African republic" , "West Africa country, capital Lome" , "W African country" , "Remaining united" , "place in Africa" .)
