Recalled fifth article about Royal Institution’s distinguished fellows (7)
I believe the answer is:
emeriti
'institution's distinguished fellows' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'recalled fifth article about royal' is the wordplay.
I cannot really understand how this works, but
'royal' could be 'er' (abbreviation for Elizabeth Regina) and 'er' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for emeriti that I've seen before include "old academics" , "honoured predecessors?" , "Former academics" , "Eg, retired professors" , "Retired title-holders" .)
