Supercharger has somewhere to sit (5)
I believe the answer is:
perch
'to sit' is the definition.
(I know that perch is a more specific form of sit)
'supercharger has' is the wordplay.
'has' indicates a hidden word.
'PERCH' is hidden within 'supercharger'.
'somewhere' is the link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for perch that I've seen before include "Bird's resting place or old measure of length" , "What angler may catch" , "Bird's roost" , "Roosting place" , "Fish and imperial measure" .)
