One guy receiving honour after backing winter transport (7)
I believe the answer is:
iceboat
'winter transport' is the definition.
'iceboat' can be an answer for 'transport' (iceboat is a kind of transport). I'm not sure about the 'winter' bit.
'one guy receiving honour after backing' is the wordplay.
'one' becomes 'i' (Roman numeral).
'guy' becomes 'cat' (American slang for man, esp in Jazz).
'receiving' is an insertion indicator.
'honour' becomes 'obe' (Order of the British Empire award).
'after backing' shows that the letters should be reversed in order.
'obe' backwards is 'ebo'.
'cat' placed around 'ebo' is 'ceboat'.
'i'+'ceboat'='ICEBOAT'
Can you help me to learn more?
(Other definitions for iceboat that I've seen before include "Craft" , "One'll break through the pack" , "it cuts through arctic seas" , "Arctic vessel" , "Ship used to clear way in polar waters" .)
