Aloft in formation display item (5)
I believe the answer is:
float
'display item' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'aloft in formation' is the wordplay.
'in formation' indicates an anagram.
'aloft' with letters rearranged gives 'FLOAT'.
Can you help me to learn more?
(Other definitions for float that I've seen before include "Lie on surface of water" , "Carnival display" , "Rest on liquid" , "Be buoyant" , "Vehicle for delivering milk" .)
