One gets aloft in ship ahead of wind (8)
I believe the answer is:
airliner
'ahead of wind' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'one gets aloft in ship' is the wordplay.
'one' becomes 'I' (Roman numeral).
'gets aloft' becomes 'ar' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'ship' becomes 'liner' (liner is a kind of ship).
'i' inserted into 'ar' is 'air'.
'air'+'liner'='AIRLINER'
Can you help me to learn more?
(Other definitions for airliner that I've seen before include "Eg, Jumbo, Concorde" , "Passenger craft" , "Large aircraft" , "Commercial plane" , "One going aloft" .)
