Aid delivered included the Spanish currency (6)
I believe the answer is:
dalasi
'currency' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'aid delivered included the spanish' is the wordplay.
I cannot really see how this works, but
'the spanish' could be 'las' (plural form of 'the' in Spanish) and 'las' is found within the answer.
an anagram of 'aid' is 'dai' which is within the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dalasi that I've seen before include "African ready" , "A bit of African mint" , "money overseas?" .)
