Wait, say, to introduce a new empty charade (10)
I believe the answer is:
importance
'wait say' is the definition.
'importance' can be an answer for 'say' (thesaurus). I'm not sure about the 'wait' bit.
'introduce a new empty charade' is the wordplay.
'introduce' becomes 'import' (I've seen this before).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'empty' suggests removing the centre.
'charade' with its middle removed is 'ce'.
'import'+'a'+'n'+'ce'='IMPORTANCE'
'to' is the link.
Can you help me to learn more?
(Other definitions for importance that I've seen before include "The -- of Being Earnest" , "See 6" , "value" , "Great significance" , "weight" .)
