One new translation flipping everything on its head? (9)

I believe the answer is:

inversion

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

'flipping everything on its head?' is the definition.
I can't judge whether this definition defines the answer.

'one new translation' is the wordplay.
'one' becomes 'i' (Roman numeral).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'translation' becomes 'version' (synonyms).
'i'+'n'+'version'='INVERSION'

Can you help me to learn more?

(Other definitions for inversion that I've seen before include "turning around" , "The opposite of" , "upsetting change" .)

I've seen this clue in The Times.
