Strange hymn about leaders of old men's organisation — it sounds the same (7)
I believe the answer is:
homonym
'same' is the definition.
(thesaurus)
'strange hymn about leaders of old men's organisation' is the wordplay.
'strange' indicates an anagram.
'about' means one lot of letters goes inside another.
'leaders of' says to take the initial letters.
The initial letters of 'old mens organisation' is 'omo'.
'hymn' with letters rearranged gives 'hnym'.
'hnym' placed around 'omo' is 'HOMONYM'.
'it sounds the' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
