Cut back, limiting transactions a bit more (5)
I believe the answer is:
extra
'a bit more' is the definition.
'extra' can be an answer for 'more' (I've seen this before). I am not sure about the 'a bit' bit.
'cut back limiting transactions' is the wordplay.
'cut' becomes 'axe' (both can mean to cancel or remove).
'back' says the letters should be written in reverse.
'limiting' means one lot of letters goes inside another.
'transactions' becomes 'tr' (I've seen this in other clues).
'axe' back-to-front is 'exa'.
'exa' enclosing 'tr' is 'EXTRA'.
Can you help me to learn more?
(Other definitions for extra that I've seen before include "Actor in crowd scene, no lines" , "Additional - run - actor - newspaper edition" , "One has no lines" , "Cricket run; unusually" , "Left over" .)
