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

'altering appearance' is the definition.
'emergence' can be an answer for 'appearance' (emergence is a kind of appearance). I am unsure of the 'altering' bit.

'from greece men' is the wordplay.
'from' indicates anagramming the letters (from the letters).
'greece'+'men'='greecemen'
'greecemen' is an anagram of 'EMERGENCE'.

Can you help me to learn more?

(Other definitions for emergence that I've seen before include "rise" , "A coming forth" , "Sudden appearance" , "Development" , "First appearance" .)
