In many enterprises, there's money (3)
I believe the answer is:
yen
'money' is the definition.
(Japanese currency)
'in many enterprises there's' is the wordplay.
'in' says the answer is hidden in the clue.
'YEN' is hidden within 'many enterprises theres'.
(Other definitions for yen that I've seen before include "Itch, desire" , "Urge" , "Itch, craving" , "Intense desire for Japanese money" , "money in Tokyo" .)
