Flowers in the sleigh (3)
I believe the answer is:
lei
'flowers' is the definition.
(a Hawaiian wreath of flowers)
'in the sleigh' is the wordplay.
'in' indicates a hidden word.
'LEI' is hidden in the letters of 'sleigh'.
(Other definitions for lei that I've seen before include "ready in Romania" , "Floral necklace" , "Band of flowers" , "Floral garland" , "cash for Romanians" .)
