Yankee, ridiculously idle, has to give up (5)
I believe the answer is:
yield
'to give up' is the definition.
(thesaurus)
'yankee ridiculously idle' is the wordplay.
'yankee' becomes 'y' (phonetic alphabet: alpha, bravo, charlie etc.).
'ridiculously' indicates an anagram (I've seen this in other clues).
'idle' anagrammed gives 'ield'.
'y'+'ield'='YIELD'
'has' is the link.
(Other definitions for yield that I've seen before include "return of financial investment" , "size of crop" , "Make a submission" , "Relinquish" , "Succumb" .)
