He's left his car behind. There's nothing unusual in that (10)
I believe the answer is:
pedestrian
'he's left his car behind there's nothing unusual in that' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he's left his car behind there's' is the wordplay.
I cannot quite see how this works, but
'car' could be 't' and 't' is present in the answer.
'there's' could be 'n' (I've seen this in other clues) and 'n' is located in the answer.
'he' could be 'des' and 'des' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pedestrian that I've seen before include "he goes for a walk" , "Boring" , "lame" , "chap on zebra could be?" , "Unimaginative" .)
