Muppet, one exiting English chauffeured car (4)
I believe the answer is:
elmo
'muppet' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'one exiting english chauffeured car' is the wordplay.
'one' becomes 'i' (Roman numeral).
'exiting' suggests deleting specific letters.
'english' becomes 'E' (abbreviation as in OED).
'chauffeured car' becomes 'limo' (I've seen this in another clue).
'e'+'limo'='elimo'
'elimo' with 'i' taken out is 'ELMO'.
Can you help me to learn more?
(Other definitions for elmo that I've seen before include "Sesame Street character - patron saint of sailors (with his own fire)" , "Saint associated with fire" , "Puppet character" , "St ...'s fire, weather phenomenon of coloured glow" , "Saint whose fire is electric!" .)
