Director to finish around four (9)

I believe the answer is:

executive

I'm a little stuck... Click here to teach me more about this clue!

'director' is the definition.
(I know that executive is a type of director)

'finish around four' is the wordplay.
'finish' becomes 'execute' (I can't justify this - if you can you should believe this answer much more).
'around' is an insertion indicator.
'four' becomes 'IV' (Roman numerals).
'execute' enclosing 'iv' is 'EXECUTIVE'.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for executive that I've seen before include "Business" , "Administrator, manager" , "Branch of government charged with putting laws, agreements etc into effect" , "Person who makes and carries out decisions" , "Person or group with management powers" .)

I've seen this clue in The Telegraph.
