Word sung twice after "Que" (4)
I believe the answer is:
'word sung twice after que' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sera that I've seen before include "Sear with serums" , "Bodily fluids (following 'que'?)" , "Hospital supplies" , "Watery liquids" .)
