Crossword Genius

Caught by tabloid's bluff (4)

Ross

I believe the answer is:

crag

Here is my best explanation:

'bluff' is the definition.
(thesaurus)

'caught by tabloid's' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'by' means one lot of letters go next to another.
'tabloid' becomes 'rag' ('rag' can be a synonym of 'tabloid').
'c'+'rag'='CRAG'
