Same thing lacking heart penned by sovereign journo (6)
I believe the answer is:
editor
'journo' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I don't see?
'same thing lacking heart penned by sovereign' is the wordplay.
I cannot quite see how this works, but
'thing' could be 'it' and 'it' is found within the answer.
'same' could be 'do' and 'do' is present in the leftover letters.
'sovereign' could be 'er' (Abbreviation for Elizabeth Regina) and 'er' is found in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for editor that I've seen before include "Director of publication" , "Person in charge of newspaper" , "Cudlipp, for one" , "Newspaperman" , "Magazine head" .)
