Crossword Genius

Ample bust upset Noel (9)

Ross

I believe the answer is:

plenteous

'ample' is the definition.
(I know that ample can be written as plenteous)

'bust upset noel' is the wordplay.
'bust' indicates an anagram.
'upset'+'noel'='upsetnoel'
'upsetnoel' with letters rearranged gives 'PLENTEOUS'.

(Other definitions for plenteous that I've seen before include "Well-provided" , "Abundant" .)

I've seen this clue in The Telegraph.
