I wear myself out in retirement, like some professors perhaps (7)
I believe the answer is:
emeriti
'some professors perhaps' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'i wear myself out in retirement' is the wordplay.
'i' becomes 'me'.
'wear' means one lot of letters goes inside another (to wear something is to be covered up by it).
'myself' becomes 'I'.
'out in' becomes 'tire' (I can't justify this - if you can you should believe this answer much more).
'retirement' is a reversal indicator (retire can mean to return or go back).
'i'+'tire'='itire'
'itire' written backwards gives 'eriti'.
'me' placed inside 'eriti' is 'EMERITI'.
'like' is the link.
Can you help me to learn more?
(Other definitions for emeriti that I've seen before include "Retired honorary professors" , "Academics retaining title after retirement" , "Former academics" , "Eg, retired professors" , "Old professors" .)
