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 quite understand how this works, but
'tesla' could be 't' (scientific unit) and 't' is found within the answer.
an anagram of 'steel' is 'setle' which is within the remaining 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" .)
