It's commendable to extol a local notability (12)
I believe the answer is:
praiseworthy
'it's commendable' is the definition.
(synonyms)
'extol a local notability' is the wordplay.
'extol' becomes 'praise' (I've seen this before).
'a local notability' becomes 'worthy' (I've seen this before. I am not sure about the 'local' bit.).
'praise'+'worthy'='PRAISEWORTHY'
'to' is the link.
Can you help me to learn more?
(Other definitions for praiseworthy that I've seen before include "Commendable" , "Laudable" , "Deserving of approval" , "Admirable" .)
