Lil embraces only a single man (6)

I believe the answer is:

lionel

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

'a single man' is the definition.
'Lionel' can be an answer for 'man'. I am not certain of the 'a single' bit.

'lil embraces only' is the wordplay.
'embraces' indicates putting letters inside.
'only' becomes 'one' (synonyms).
'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" , "Oil Len badly for another man" , "-- Bart; -- Richie" , "- Bart, (Oliver!)" .)

I've seen this clue in the Evening Standard.
