Restricted a part of car with raised temperature (5)
I believe the answer is:
taboo
'restricted' is the definition.
(thesaurus)
'a part of car with raised temperature' is the wordplay.
'part of' is an insertion indicator (part of the inside).
'car' becomes 't'.
'with raised temperature' becomes 'boo' (I can't explain this - if you can you should believe this answer much more).
't'+'boo'='tboo'
'a' going into 'tboo' is 'TABOO'.
Can you help me to learn more?
(Other definitions for taboo that I've seen before include "Not to be mentioned" , "Subject to prohibition" , "Prohibited by social custom" , "By religion or custom, not to be done or touched" , "Not allowed, forbidden, proscribed" .)
