So slur I spread about scoundrel is libellous? (10)
I believe the answer is:
scurrilous
'libellous?' is the definition.
'so slur i spread about scoundrel' is the wordplay.
'spread' is an anagram indicator.
'about' is an insertion indicator.
'scoundrel' becomes 'cur' (I've seen this before).
'so'+'slur'+'i'='sosluri'
'sosluri' with letters rearranged gives 'srilous'.
'srilous' placed around 'cur' is 'SCURRILOUS'.
'is' is the link.
(Other definitions for scurrilous that I've seen before include "Grossly insulting" , "Unjustifiably defamatory" , "Humorously insulting" , "Obscenely slanderous" , "Scandalously damaging" .)
