Peter Sellers somewhat brusque? (5)

I believe the answer is:

terse

'brusque?' is the definition.
(thesaurus)

'peter sellers somewhat' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'TERSE' is hidden in the letters of 'peter sellers'.

(Other definitions for terse that I've seen before include "Using few words" , "Trees (anag.)" , "Aphoristic" , "Crisp and brief" , "Reset to be pithy" .)

I've seen this clue in The Sun and The Telegraph.
