KrisKross has to chase career / job etc. in the end (9)
I believe the answer is:
objective
'the end' is the definition.
(objective is a kind of end)
'kriskross has to chase career job etc' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'job' is 'obj' which is present in the answer.
an anagram of 'etc' is 'ect' which is present in the answer.
The remaining letters 'ive' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for objective that I've seen before include "Aim - impartial" , "relating to external phenomena" , "Not emotionally involved" , "Dispassionate" , "Goal, intent" .)
