Original sinner right continually (4)

I believe the answer is:

ever

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

'continually' is the definition.
(I've seen this before)

'original sinner right' is the wordplay.
'original sinner' becomes 'eve' (Biblical figure. I am not sure about the 'original' bit.).
'right' becomes 'r' (common abbreviation).
'eve'+'r'='EVER'

Can you help me to learn more?

(Other definitions for ever that I've seen before include "Continually" , "At all times, always" , "Continuously" , "To the end of time" , "Eternity" .)

I've seen this clue in The Sun.
