Animal transport question kept coming back (6)
I believe the answer is:
howdah
'animal transport' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'question kept coming back' is the wordplay.
'question' becomes 'how' (how is a question word).
'kept' becomes 'had' (I've seen this in another clue).
'coming back' shows that the letters should be reversed in order.
'had' backwards is 'dah'.
'how'+'dah'='HOWDAH'
Can you help me to learn more?
(Other definitions for howdah that I've seen before include "Does it get you high for a trip" , "something to accommodate Jumbo passenger?" , "Seat fixed on an elephant" , "Elephant rider's chair" , "Who had a change on the elephant's back" .)
