Crossword Genius

It's peculiar, butler says, in a complicated sort of way (10)

Ross

I believe the answer is:

abstrusely

'in a complicated sort of way' is the definition.
(abstrusely means in a complicated or difficult way)

'it's peculiar butler says' is the wordplay.
'it's peculiar' indicates anagramming the letters (a peculiar or strange ordering of the letters).
'butler'+'says'='butlersays'
'butlersays' anagrammed gives 'ABSTRUSELY'.
