Odd couple from Eire chasing motor mechanic (8)
I believe the answer is:
engineer
'mechanic' is the definition.
(type of engineer)
'odd couple from eire chasing motor' is the wordplay.
I cannot really see how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for engineer that I've seen before include "Arrange - contrive" , "Deviser" , "One can be chemical, civil or mechanical" , "Mechanic" , "Person who uses scientific knowledge to solve practical problems" .)
