Litter project round midday, one of five (9)
I believe the answer is:
palanquin
'litter' is the definition.
(litter carried as a form of transport)
'project round midday one of five' is the wordplay.
'project' becomes 'alap' (I am not sure about this - if you are sure you should believe this answer much more).
'round' says the letters should be written backwards.
'midday' becomes 'n' (abbreviation for noon).
'one of five' becomes 'quin' (short for quintuplet, one of five children).
'alap' back-to-front is 'pala'.
'pala'+'n'+'quin'='PALANQUIN'
Can you help me to learn more?
(Other definitions for palanquin that I've seen before include "Shoulder-borne litter for one person" , "Box carried on poles" .)
