Why a report is strangely admirable (12)
I believe the answer is:
praiseworthy
'admirable' is the definition.
(I've seen this before)
'why a report is strangely' is the wordplay.
'strangely' indicates anagramming the letters.
'why'+'a'+'report'+'is'='whyareportis'
'whyareportis' is an anagram of 'PRAISEWORTHY'.
(Other definitions for praiseworthy that I've seen before include "Deserving of approval" , "Laudable" , "Admirable" , "Commendable" .)
