Foul smelling taxis here? (4)
I believe the answer is:
rank
This clue could be a double definition.
'foul' is the first definition.
(synonyms)
'smelling taxis here?' is the second definition.
'rank' can be an answer for 'smelling' (thesaurus). I am not sure about the 'taxis here?' bit.
Can you help me to learn more?
(Other definitions for rank that I've seen before include "High social standing" , "It could be major row" , "Where taxis wait - foul" , "Row of people standing abreast" , "The military row is coarsely overgrown" .)
