Precious lump inspired by playing Othello (5)
I believe the answer is:
ingot
'precious lump' is the definition.
'ingot' can be an answer for 'lump' (I have seen 'Lump of metal' mean 'ingot' so perhaps 'lump' could also mean 'ingot'). I'm not sure about the 'precious' bit.
'inspired by playing othello' is the wordplay.
'inspired by' indicates the answer is hidden within the clue (the clue has breathed in or 'inspired' the answer).
'INGOT' can be found hidden inside 'playing othello'.
Can you help me to learn more?
(Other definitions for ingot that I've seen before include "Moulded metal bar" , "Gold Stick" , "Cast metal brick" , "Metal casting" , "expensive block" .)
