After the end of March, I'm the fellow you want (3)
I believe the answer is:
him
'fellow you want' is the definition.
The definition suggests a singular noun which matches the answer.
'after the end of march i'm' is the wordplay.
'after' means one lot of letters go next to another.
'the end of' says to take the final letters.
The last letter of 'march' is 'h'.
'h' next to 'im' is 'HIM'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for him that I've seen before include "Objective male pronoun" , "Proper character" , "That man" .)
