Engineers offend, leaving in consequence (6)

I believe the answer is:

result

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

'consequence' is the definition.
(I know that consequence can be written as result)

'engineers offend leaving' is the wordplay.
'engineers' becomes 'res'.
'offend leaving' becomes 'ult' (I can't justify this - if you can you should give a lot more credence to this answer).
'res'+'ult'='RESULT'

'in' is the link.

Can you help me to learn more?

(Other definitions for result that I've seen before include "Ulster (anag) - outcome" , "Effect of lustre" , "Effect - outcome" , "End - issue" , "Final score" .)

I've seen this clue in The Independent.
