Car repairs botched with loss of power (6)
I believe the answer is:
sierra
'loss of power' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'car repairs botched' is the wordplay.
I cannot quite understand how this works, but
'car' could be 'rr' (Rolls Royce) and 'rr' is located in the answer.
This explanation may well be incorrect...
'with' acts as a link.
Can you help me to learn more?
(Other definitions for sierra that I've seen before include "Jagged mountains - code word for S" , "A range of mountains in Spain" , "Nato alphabet 'S'" , "One range" , "letter read out on the radio" .)
