How a liar can make a bit of money (4)
I believe the answer is:
lira
'a bit of money' is the definition.
'lira' can be an answer for 'money' (I have seen 'old money' mean 'lira' so perhaps 'money' could also mean 'lira'). I am not certain of the 'a bit of' bit.
'how a liar' is the wordplay.
'how' indicates anagramming the letters (I've seen this in other clues).
'liar' is an anagram of 'LIRA'.
'can make' is the link.
Can you help me to learn more?
(Other definitions for lira that I've seen before include "Old Italian coin" , "Old unit of Italian money" , "Former unit of money in Italy" , "Unit of money for 26 across" , "Former Italian currency unit" .)
