The aims of termini (4)
I believe the answer is:
ends
This clue is a double definition.
'the aims' is the first definition.
(I've seen this before)
'termini' is the second definition.
(I've seen this in another clue)
'of' is the link.
(Other definitions for ends that I've seen before include "Halts" , "Brings to a close" , "Borders" , "Desired results" , "They may justify the means" .)
