They come in hundreds, as in a recent survey (5)
I believe the answer is:
cents
'they come in hundreds' is the definition.
The definition suggests an adverb but the answer is not.
'in a recent survey' is the wordplay.
'in' says the answer is hidden in the clue.
'CENTS' can be found hidden inside 'recent survey'.
'as' is the link.
Can you help me to learn more?
(Other definitions for cents that I've seen before include "American coins" , "Hundredths of dollar" , "US money, e.g." , "Fractions of dollar" , "money abroad" .)
