Singer from off-and-on screen embraced by performer (8)

'singer' is the definition.
(accentor is a kind of birdanimal)

'off-and-on screen embraced by performer' is the wordplay.
'off-and-on screen' becomes 'cen' (I can't explain this - if you can you should believe this answer much more).
'embraced by' indicates putting letters inside.
'performer' becomes 'actor' (actor is a kind of performer).
'cen' placed inside 'actor' is 'ACCENTOR'.

'from' is the link.

Can you help me to learn more?
