I don't like this starter of toasted Asian bread (4)
I believe the answer is:
baht
'asian bread' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'i don't like this starter of toasted' is the wordplay.
'i don't like' becomes 'bah' (I can't explain this - if you can you should believe this answer much more).
'this starter of' indicates taking the first letters.
The first letter of 'toasted' is 't'.
'bah'+'t'='BAHT'
Can you help me to learn more?
(Other definitions for baht that I've seen before include "Thai currency unit" , "Asian money" , "Thai money" , "Monetary unit in Thailand" , "Tin" .)
