Fix Tesla with damaged steel casing (6)
I believe the answer is:
settle
'fix' is the definition.
(fix a problem, settle the matter)
'tesla with damaged steel casing' is the wordplay.
I cannot really see how this works, but
'tesla' could be 't' (scientific unit) and 't' is found in the answer.
an anagram of 'steel' is 'setle' which is located in the left over letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for settle that I've seen before include "Resolve or reach an agreement" , "High-backed bench" , "Make home, put down roots" , "Resolve; alight" , "Resolve - to pay one's debts" .)
