Tender name broadcast as expression of love (10)
I believe the answer is:
endearment
'expression of love' is the definition.
(I've seen this before)
'tender name broadcast' is the wordplay.
'broadcast' indicates anagramming the letters.
'tender'+'name'='tendername'
'tendername' anagrammed gives 'ENDEARMENT'.
'as' acts as a link.
(Other definitions for endearment that I've seen before include "Expression of love" , "Word of affection" , "Affectionate word" , "Term of affection" , "Affectionate utterance" .)
