Just money for transport, we hear (4)
I believe the answer is:
fair
'just' is the definition.
(just can mean fair in the sense of showing justice)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for fair that I've seen before include "Just; beautiful; blond" , "the place for a roundabout" , "Unbiased; carnival" , "Just; fete" , "Just; gala" .)
