Prevalent, rife (10)
I believe the answer is:
widespread
I believe this is a double definition.
'prevalent' is the first definition.
(I've seen this before)
'rife' is the second definition.
(thesaurus)
(Other definitions for widespread that I've seen before include "common" , "Sweeping" , "broad" , "available to lots of people" , "Extensive" .)
