Croon head off to uplifting cast piece (5)
I believe the answer is:
ingot
'cast piece' is the definition.
'ingot' can be an answer for 'cast' (thesaurus). I am not sure about the 'piece' bit.
'croon head off to uplifting' is the wordplay.
'croon' becomes 'sing' (I've seen this in another clue).
'head off' means to remove the first letter (the first letter or 'head' is removed).
'uplifting' says the letters should be written in reverse.
'to' backwards is 'ot'.
'sing' with its initial letter taken off is 'ing'.
'ing'+'ot'='INGOT'
Can you help me to learn more?
(Other definitions for ingot that I've seen before include "Seize quickly; steal" , "this must be cast" , "A lump of metal, perhaps gold" , "Piece of cast metal" , "Mass of cast metal" .)
