TERMINATIONS  IN  -ate  AND  -ite. 
The  accent  follows  the  general  rule  (as  a'cetate,  vanadate); 
in  the  following  words  the  accent  is  thrown  back  (as  a'  b  i  e  t  a  t  e, 
a'lcoholate,  a'cetonate,  a'ntimonite). 
TERMINATIONS  IN  -id  (FORMERLY  -ide). 
The  final  e  is  dropped  in  every  case  and  the  syllable  pronounced 
id  (as  chlo'rid,  Tod  id,  hy'drid,  o'xid,  hydrox'id,  su'  1- 
fid,  a' mid,  a7  nil  id,  mure'xid). 
terminations  in  -ane,  -ene,  -ine  and  -one. 
The  vowel  of  these  syllables  is  invariably  long  (as  me'thane, 
e' thane,  na'phthalene,  anthracene,  proline,  qui'- 
none,  a'cetone,  ke'tone). 
A  few  dissyllables  have  no  distinct  accent  (as  benzene,  xy- 
lene, cetene), 
The  termination  -ine  is  used  only  in  the  case  of  doubly  unsatu- 
rated hydrocarbons,  according  to  Hofmann's  grouping  (as  p  r  o  p  i  n  e). 
terminations  in  -in. 
In  names  of  chemical  elements  and  compounds  of  this  cless, 
which  includes  all  those  formerly  ending  in  -ine  (except  doubly 
unsaturated  hydrocarbons)  the  final  e  is  dropped,  and  the  syllable 
pronounced  -in  (as  chlo'rin,  bro'min,  etc.,  a7  mi  n,  a7  nil  In, 
mo'rphin,  q  u  V  n  i  n,  v  a  n  V  1 1  i  n,  a  1 1  o  x  a'  n  1 1  n,  a  b  s  V  n  t  h  l  n, 
emu7  Is  in,  ca'ffein,  co'cain). 
terminations  in  -ol. 
This  termination,  in  the  case  of  specific  chemical  compounds,  is 
used  exclusively  for  alcohols,  and  when  so  used  is  never  followed  by 
a  final  e.  The  last  syllable  is  pronounced  -ol  (as  g  1  y'  c  6  1,  p  h  er  n  5  1, 
ere' sol,    thy'mol  (ti),  gly'cerol,  qui'nol. 
Exceptions:  alcohol,  a'rgol. 
terminations  in  -ole. 
This  termination  is  always  pronounced  -ole,  and  its  use  is  limited 
to  compounds,  which  are  not  alcohols  (as  V  n  d  6 1  e). 
terminations  in  -yl. 
No  final  e  is  used ;  the  syllable  is  pronounced  yl  (as  a'cety  1, 
a'myl,  c  e' r  o  t  y  1,  c  e' ty  1,  e'thyl).
