Curate claps wildly for lavish show (11)
I believe the answer is:
spectacular
'lavish show' is the definition.
(a spectacular is an amazing show)
'curate claps wildly' is the wordplay.
'wildly' indicates anagramming the letters.
'curate'+'claps'='curateclaps'
'curateclaps' with letters rearranged gives 'SPECTACULAR'.
'for' acts as a link.
(Other definitions for spectacular that I've seen before include "Extravaganza" , "Very striking or dramatic" , "Thrilling in effect" , "Visually astounding" , "Impressive, striking" .)
