Quarrel with a head of government in Parisian street (5)
I believe the answer is:
argue
'quarrel' is the definition.
(thesaurus)
'a head of government in parisian street' is the wordplay.
'head of' indicates taking the first letters.
'in' means one lot of letters goes inside another.
'parisian street' becomes 'rue'.
The first letter of 'government' is 'g'.
'g' going inside 'rue' is 'rgue'.
'a'+'rgue'='ARGUE'
'with' acts as a link.
(Other definitions for argue that I've seen before include "contradict" , "Discuss, contend" , "Quarrel or disagree" , "Present the case for" , "Wrangle" .)
