Meticulous cabbie’s passenger in public highway (12)
I believe the answer is:
thoroughfare
'public highway' is the definition.
'thoroughfare' can be an answer for 'highway' (I've seen this before). I'm unsure of the 'public' bit.
'meticulous cabbie's passenger' is the wordplay.
'meticulous' becomes 'thorough' (I've seen this before).
'cabbie's passenger' becomes 'fare' (I've seen this in another clue).
'thorough'+'fare'='THOROUGHFARE'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for thoroughfare that I've seen before include "Access - road" , "Public road" , "Main road" , "Public way or street" , "Road or path" .)
