Get a loan from George (6)
I believe the answer is:
borrow
'get a loan' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for borrow that I've seen before include "Take temporarily" , "Obtain something on loan" , "In library, ask for" , "Go to the bank manager" , "Scrounge" .)
