Ordinary, dull (7)
I believe the answer is:
humdrum
I believe this is a double definition.
'ordinary' is the first definition.
(I've seen this before)
'dull' is the second definition.
(similar in meaning)
(Other definitions for humdrum that I've seen before include "Dull (of existence)" , "Run-of-the-mill" , "Dull, monotonous" , "Mundane, commonplace" , "Droning sounds" .)
