Normal; commonplace (8)
I believe the answer is:
ordinary
This clue is a double definition.
'normal' is the first definition.
(I've seen this before)
'commonplace' is the second definition.
(similar in meaning)
(Other definitions for ordinary that I've seen before include "Normal, mundane" , "simple charge" , "Run-of-the-mill" , "Commonplace, avergae" , "standard" .)
