Is set back by my French name (5)
I believe the answer is:
simon
'name' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I don't see?
'is set back by my french' is the wordplay.
'set back' says the letters should be written backwards.
'by' says to put letters next to each other.
'my french' becomes 'mon' ('my' in French).
'is' in reverse letter order is 'si'.
'si'+'mon'='SIMON'
Can you help me to learn more?
(Other definitions for simon that I've seen before include "A simple character in nursery rhyme" , "- Bol'var, S. American liberator" , "- and Garfunkel" , "He's simple in rhyme" , "Sir -- Rattle, conductor" .)
