Much Ado project is a thrill ride (9)
I believe the answer is:
adventure
'thrill ride' is the definition.
'adventure' can be an answer for 'thrill' (I have seen 'The thrill' mean 'adventure' so perhaps 'thrill' could also mean 'adventure'). I am not certain of the 'ride' bit.
'much ado project' is the wordplay.
'much' means to remove the last letter (much but not all of the word).
'project' becomes 'venture' (venture is a kind of project).
'ado' with its last letter removed is 'ad'.
'ad'+'venture'='ADVENTURE'
'is a' acts as a link.
Can you help me to learn more?
(Other definitions for adventure that I've seen before include "Dangerous undertaking" , "The thrill" , "risky undertaking" , "Escapade" , "Risky or exciting experience" .)
