Starchy ingredient of Xmas pudding (4)
I believe the answer is:
spud
'starchy ingredient' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'of xmas pudding' is the wordplay.
'of' indicates the answer is hidden within the clue.
'SPUD' is hidden within 'xmas pudding'.
Can you help me to learn more?
(Other definitions for spud that I've seen before include "Starchy bit of food" , "short, stocky person" , "veg" , "The common potato" , "King Edward, e.g." .)
