Young Obama's first belt? (5)
I believe the answer is:
sasha
'young' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
'obama's first belt?' is the wordplay.
'obama' becomes 'a' (I can't justify this - if you can you should give a lot more credence to this answer).
'first' means one lot of letters go next to another.
'belt?' becomes 'sash' (sash is a type of belt).
'a' put after 'sash' is 'SASHA'.
Can you help me to learn more?
(Other definitions for sasha that I've seen before include "young man from Russia" , "Russian boy" , "Possible Russian" .)
