Half sensed satire Ionian put together would be a big success (9)
I believe the answer is:
sensation
'success' is the definition.
(thesaurus)
'half sensed satire ionian put together would be a big' is the wordplay.
I cannot really understand how this works, but
'put' could be 'sat' (both can mean positioned or placed) and 'sat' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sensation that I've seen before include "Awareness of a stimulus, such as heat or pain" , "Physical feeling or perception" , "Feeling; thrilling person or thing" , "Feeling, awareness of stimulation" , "Crowd puller" .)
