Ordinary or widespread (6)
I believe the answer is:
common
I believe this clue is a double definition.
'ordinary' is the first definition.
(associated in meaning)
'widespread' is the second definition.
(I've seen this before)
(Other definitions for common that I've seen before include "Met with frequently" , "Plentiful or vulgar" , "Widespread; vulgar" , "Familiar or not refined" , "for everyone" .)
