Try to finish? Always, it's said (9)
I believe the answer is:
endeavour
'try' is the definition.
(endeavouring is a kind of trying)
'finish? always it's said' is the wordplay.
I cannot quite understand how this works, but
'finish?' could be 'end' (finishing is a kind of ending) and 'end' is found in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found in the answer.
This may be the basis of clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for endeavour that I've seen before include "Industrious effort" , "Try - Captain Cook's vessel" , "Try - Cook's ship" , "Enterprise; earnest effort" , "Strive - Inspector Morse's first name" .)
