Innocent and feeble in praise (9)
I believe the answer is:
blameless
'innocent' is the definition.
(similar in meaning)
'feeble in praise' is the wordplay.
'feeble' becomes 'lame' (synonyms).
'in' is an insertion indicator.
'praise' becomes 'bless' (I've seen this before).
'lame' put within 'bless' is 'BLAMELESS'.
'and' is the link.
(Other definitions for blameless that I've seen before include "Irreproachable" , "Without culpability, innocent" .)
