In the cold, abandon trade fair, having seen half (6)
I believe the answer is:
expose
'in the cold abandon trade' is the definition.
I can't tell whether this defines the answer.
'fair having seen half' is the wordplay.
'fair' becomes 'expo' (an expo is a type of large exhibition).
'having' means one lot of letters go next to another.
'half' suggests halving the letters.
'seen' with half the letters taken is 'se'.
'expo'+'se'='EXPOSE'
Can you help me to learn more?
(Other definitions for expose that I've seen before include "Show up" , "Uncover, expose to view" , "Make visible or apparent" , "Reveal or unmask" , "Abandon" .)
