Mundane, ordinary (8)
I believe the answer is:
everyday
This clue is a double definition.
'mundane' is the first definition.
(I know that mundane can be written as everyday)
'ordinary' is the second definition.
(similar in meaning)
(Other definitions for everyday that I've seen before include "Mundane, ordinary" , "Run-of-the-mill" , "Happening seven times a week" , "Ordinary, for regular use" , "Common or usual" .)
