Depressed with range of knowledge shown by tabloid (6)
I believe the answer is:
sunken
'depressed' is the definition.
(thesaurus)
'range of knowledge shown by tabloid' is the wordplay.
'range of knowledge' becomes 'ken' (I've seen this before).
'shown by' is a charade indicator (letters next to each other).
'tabloid' becomes 'sun' (The Sun, UK newspaper).
'ken' after 'sun' is 'SUNKEN'.
'with' is the link.
(Other definitions for sunken that I've seen before include "Deeply recessed" , "(Of eyes) recessed" , "At a lower level than the surroundings" , "beneath the sea" , "Bas relief" .)
