'sibling removing bronze head being different' is the definition.
I can't tell whether this defines the answer.

'sibling removing bronze head being different' is the wordplay.
'sibling' becomes 'brother' (I've seen this before).
'removing' indicates named letters should be taken away.
'bronze' becomes 'br' (abbreviation for bronze).
'head being different' becomes 'ness' (I can't explain this - if you can you should give a lot more credence to this answer).
'brother' with 'br' taken away is 'other'.
'other'+'ness'='OTHERNESS'

Can you help me to learn more?

(Other definitions for otherness that I've seen before include "Quality of being different" , "Distinctive quality" .)
