Invest in merger of Chelmsford and Aintree? (6)
I believe the answer is:
ordain
'invest' is the definition.
(I know that ordain is a kind of invest)
'in merger of chelmsford and aintree?' is the wordplay.
I cannot really understand how this works, but
'in' is within the answer.
'of' could be 'o' and 'o' is found in the answer.
The remaining letters 'rda' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ordain that I've seen before include "Inroad (anag.)" , "Appoint as priest" , "Establish" , "Destine" , "Install as priest" .)
