  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Azole  \Az"ole\,  n.  [From  {Azote}.]  (Org.  Chem.) 
  Any  of  a  large  class  of  compounds  characterized  by  a 
  five-membered  ring  which  contains  an  atom  of  nitrogen  and  at 
  least  one  other  noncarbon  atom  (nitrogen,  oxygen,  sulphur). 
  The  prefixes  furo-,  thio,  and  pyrro-  are  used  to  distinguish 
  three  subclasses  of  azoles,  which  may  be  regarded  as  derived 
  respectively  from  furfuran,  thiophene,  and  pyrrol  by 
  replacement  of  the  {CH}  group  by  nitrogen;  as  furo-monazole. 
  Names  exactly  analogous  to  those  for  the  azines  are  also 
  used  as  oxazole  diazole  etc
