Men of the same calling (9)
I believe the answer is:
namesakes
'men' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'same calling' is the wordplay.
I cannot quite see how this works, but
an anagram of 'same' is 'ames' which is within the answer.
This may be the basis of the clue (or it may be nonsense).
'of the' acts as a link.
Can you help me to learn more?
(Other definitions for namesakes that I've seen before include "with identical titles" , "People addressed in the same way" .)
