orthodox: [16] Greek orthós meant ‘straight, correct’ (it enters into numerous English compounds, including orthography ‘correct spelling’ [15] and orthopaedic [19]). Greek dóxa meant ‘opinion’; it was derived from the verb dokein ‘think’. Put them together and you got orthódoxos ‘having the right opinion’, which passed into English via ecclesiastical Latin orthodoxus.
