Succinct as a gorgeous child? (5,3,5)
I believe the answer is:
short and sweet
'succinct' is the definition.
(thesaurus)
'a gorgeous child?' is the wordplay.
I cannot quite see how this works, but
'a' could be 'an' and 'an' is found within the answer.
This explanation may well be incorrect...
'as' acts as a link.
Can you help me to learn more?
(Other definitions for short and sweet that I've seen before include "Nice while it lasted" , "Quickly and to the point" , "Unexpectedly pithy" , "Curt" , "briefly pleasant" .)
