Outside in deluge, fellow gets drier in the car (8)
I believe the answer is:
demister
'drier in the car' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'outside in deluge fellow' is the wordplay.
'outside in' suggests removing the centre (only the letters on the outside).
'fellow' becomes 'mister' (I've seen this in another clue).
'deluge' with its centre removed is 'de'.
'de'+'mister'='DEMISTER'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for demister that I've seen before include "One gives a clear view" , "Device for removing condensation from a windscreen" , "Remover of condensation" , "one good at clearing" , "control of car" .)
