Ring the bell and wave e-tag at the turnpike (8)
I believe the answer is:
tollgate
'the turnpike' is the definition.
(thesaurus)
'ring the bell and wave e-tag' is the wordplay.
'ring the bell' becomes 'toll' (I've seen this in another clue).
'and' means one lot of letters go next to another.
'wave' is an anagram indicator (I've seen 'waving' mean this (letters wave around)).
'e'+'tag'='etag'
'etag' anagrammed gives 'gate'.
'toll'+'gate'='TOLLGATE'
'at' acts as a link.
(Other definitions for tollgate that I've seen before include "Barrier where travellers pay" , "Road barrier where payment is due" , "Road barrier with charges" , "Through which travellers must pay to pass" , "Where travellers must pay to continue their journey" .)
