Venezuelan banker is womble (7)
I believe the answer is:
orinoco
This clue might be a double definition.
'venezuelan banker' is the first definition.
'orinoco' can be an answer for 'banker' (I've seen this before). I am not sure about the 'venezuelan' bit.
'womble' is the second definition.
(character in The Wombles)
'is' acts as a link.
Can you help me to learn more?
(Other definitions for orinoco that I've seen before include "Common character" , "Great river in the north of S America, flows through Venezuela" , "large flow of water" , "River, rising in Venezuela, forming part of its border with Colombia and flowing into the Atlantic" , "resident on Wimbledon Common" .)
