Completely detached from the very beginning (5,3)

Ross

I believe the answer is:

right off

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

'completely detached from' is the definition.
I can't judge whether this defines the answer.

'very beginning' is the wordplay.
'very' becomes 'right' (synonyms).
'beginning' becomes 'off' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'right'+'off'='RIGHT OFF'

'the' acts as a link.

Can you help me to learn more?

(Other definitions for right off that I've seen before include "Without delay" , "Immediately" .)
