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

'changed suburb' is the definition.
The definition suggests a past participle verb which matches the answer.

'sadly fit in greed' is the wordplay.
'sadly' is an anagram indicator.
'fit'+'in'+'greed'='fitingreed'
'fitingreed' anagrammed gives 'GENTRIFIED'.

'to' is the link.

Can you help me to learn more?

(Another definition for gentrified that I've seen is " such an improved area?".)
