New balls seem squeaky clean (9)
I believe the answer is:
blameless
'squeaky clean' is the definition.
'blameless' can be an answer for 'clean' (thesaurus). I'm not certain of the 'squeaky' bit.
'new balls seem' is the wordplay.
'new' is an anagram indicator.
'balls'+'seem'='ballsseem'
'ballsseem' is an anagram of 'BLAMELESS'.
Can you help me to learn more?
(Other definitions for blameless that I've seen before include "Irreproachable" , "Without culpability, innocent" .)
