Ordinary, basic (3-8)
I believe the answer is:
bog-standard
This clue is a double definition.
'ordinary' is the first definition.
(I've seen this before)
'basic' is the second definition.
(I've seen this before)
(Other definitions for bog-standard that I've seen before include "Everyday" , "Basic -- ordinary (slang)" , "Utterly ordinary" , "Run-of-the-mill" .)
