I'll change round a single man's name (6)

I believe the answer is:

lionel

I'm a little stuck... Click here to teach me more about this clue!

'single man's name' is the definition.
The definition suggests a singular noun which matches the answer.

'i'll change round a' is the wordplay.
'change' is an anagram indicator.
'round' is an insertion indicator.
'a' becomes 'one'.
'ill' anagrammed gives 'lil'.
'lil' going around 'one' is 'LIONEL'.

Can you help me to learn more?

(Other definitions for lionel that I've seen before include "Boy" , "Guy" , "Blair possibly" , "- Bart, (Oliver!)" , "Oil Len badly for another man" .)
