Eradicate source of nationalism potentially? (10)

I believe the answer is:

deracinate

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

'eradicate source of nationalism potentially?' is the definition.
I can't judge whether this defines the answer.

'eradicate source of nationalism potentially?' is the wordplay.
'source of' indicates taking the first letters (the start - or source - of the word).
'potentially?' is an anagram indicator (letters have the potential to spell a new word).
The initial letter of 'nationalism' is 'n'.
'eradicate'+'n'='eradicaten'
'eradicaten' anagrammed gives 'DERACINATE'.

Can you help me to learn more?

(Another definition for deracinate that I've seen is " Uproot".)

I've seen this clue in The Guardian.
