Orthodox (6)

Ross

I think it could be either:

normal

proper

'orthodox' is the definition.
(thesaurus)

This is all the clue.

(Other definitions for normal that I've seen before include "Conforming to what is usual" , "Usual; at right angles" , "Accustomed" , "Usual - sane" , "Usual, not extraordinary" .)

I've seen this clue in the Wall Street Journal, the Newsday.com and The Telegraph.
