Old landholders in Athens displaced (6)
I believe the answer is:
'old landholders' is the definition.
The answer and definition can be both people as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'athens displaced' is the wordplay.
'displaced' is an anagram indicator.
'athens' is an anagram of 'THANES'.
'in' is the link.
Can you help me to learn more?
