Daughter gets rotten roll, a bit of bread abroad (6)
I believe the answer is:
dollar
'bit of bread abroad' is the definition.
I can't judge whether this definition defines the answer.
'daughter gets rotten roll a' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'gets' indicates putting letters inside.
'rotten' is an anagram indicator.
'roll'+'a'='rolla'
'rolla' anagrammed gives 'ollar'.
'd' put within 'ollar' is 'DOLLAR'.
Can you help me to learn more?
(Other definitions for dollar that I've seen before include "American currency" , "US monetary unit" , "Monetary unit - town in Clackmannanshire" , "American's ready" , "US currency" .)
