Tackles jeep cleverly and he makes very high repairs (11)
I believe the answer is:
steeplejack
'he makes very high repairs' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'tackles jeep cleverly' is the wordplay.
'cleverly' indicates anagramming the letters (a clever or tricky version of the letters).
'tackles'+'jeep'='tacklesjeep'
'tacklesjeep' anagrammed gives 'STEEPLEJACK'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for steeplejack that I've seen before include "One working up tall structures" , "one used to effecting repairs aloft?" , "Climber of tall structures" , "One working at heights" , "Worker on tall chimneys etc" .)
