Incompletely strive to fix things! (5)
I believe the answer is:
rivet
'fix things' is the definition.
'rivet' can be an answer for 'fix' (riveting is a kind of fixing). I am not certain of the 'things' bit.
'incompletely strive to' is the wordplay.
'RIVET' is hidden in amongst the letters.
However, I am not sure how this is indicated.
Can you help me to learn more?
(Other definitions for rivet that I've seen before include "Metal fastening pin" , "Captivate" , "Completely engross; pin" , "Fasten with metal pins - enthral" , "join securely" .)
