Catch sight of The Borders' tourist traps coming back (4)
I believe the answer is:
spot
'catch sight of' is the definition.
(to spot is to notice or catch sight of)
'the borders' tourist traps coming back' is the wordplay.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'borders' tourist traps' becomes 'ops' (I can't justify this - if you can you should give a lot more credence to this answer).
'coming back' is a reversal indicator.
't'+'ops'='tops'
'tops' reversed gives 'SPOT'.
Can you help me to learn more?
(Other definitions for spot that I've seen before include "Dirty blemish" , "Identify" , "Dot, stain" , "[NIGHTCLUB]" , "Notice - fictional puppy" .)
