Fatuous characters in Twain anecdote (5)

Ross

I believe the answer is:

inane

'fatuous' is the definition.
('inane' can be a synonym of 'fatuous')

'characters in twain anecdote' is the wordplay.
'characters in' indicates a hidden word.
'INANE' can be found hidden inside 'twain anecdote'.

(Other definitions for inane that I've seen before include "Fatuous, asinine" , "Idiotic" , "Frivolous" , "Foolish, fatuous" , "Dull-witted" .)

I've seen this clue in The Times.
