Mother reaches one city, Georgia another (6)
I believe the answer is:
malaga
'city georgia another' is the definition.
I can't judge whether this defines the answer.
'mother reaches one' is the wordplay.
'mother' becomes 'ma' (ma can mean mother).
'reaches' becomes 'lag' (I can't justify this - if you can you should believe this answer much more).
'one' becomes 'a' (a thing is one thing).
'ma'+'lag'+'a'='MALAGA'
Can you help me to learn more?
(Other definitions for malaga that I've seen before include "Resort in Andalusia" , "Spanish port and resort town" , "Costa del Sol resort" , "City of Andalusia" , "where Spanish sailor lands?" .)
