Type of column (5)
'type of column' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for doric that I've seen before include "hairdo tips costly, for the most part" , "Greek architectural order" , "Style of column" , "Greek architectural style" , "In a classical Greek style of architecture" .)
(Another definition for oped that I've seen is " article in paper".)
