Introduction:  Spoken tones are governed by several rules that are summarized graphically in the tone chart.  Here we shall comment briefly on the two kinds of syllables in Lao.  The first type is "Smooth or Live."  They end in a long vowel or a final -m, -n, -N, -l, -r, -y, -w.  The second type is "Checked or Dead" syllables: syllables ending in - p, -t, -k, glottal stop (sudden closure of the glottis).  The reason for these names has to do with the air flow out of the oral cavity.  A checked or stopped syllable is made "dead" by the lips (-p), the tip/blade of the tongue (-t), the back of the tongue (-k), or closure of the glottis (?).  A "live" syllable is, by default, "not dead."  That is the syllable can be continued or  kept "alive" by continuous air flow.  The terms "live" and "dead" come from Lao terms "pen" and "taay" respectively.   They correspond to the phonetic terms "smooth" and "checked."   The tone chart is divided vertically along the lines of live and dead.  The first question the learner should ask is:  "Is the syllable I am reading live or dead?"  Then the learner should ask,  "Is the initial consonant High, Middle, or Low Class?"  If it is one of the latter three, then the next question is: "Is there a written tone mark?"  These three questions then lead to the final answer found in one of the boxes in the tone chart.  Keep these questions in mind as you engage yourself in the following exercises.

Su4uN/High Class Consonants

   The first group of consonants to learn is the su4uN class.  The su4uN consonants are pronounced with a low rising tone.
                     
Consonants: 0 l 4 z / s
Names: khO4O sO4O thO4O phO4O fO4O hO4O
                      
   If we list the su4uN and ta#m/Low Class consonants side by side, we see that there are su4uN symbols corresponding to some ta#m symbols.
                    
su4uN   ta#m  
0 khO4O 7 khO2O
l sO4O - sO2O
4 thO4O m thO2O
z phO4O r phO2O
/ fO4O 2 fO2O
s hO4O I hO2O
              
   If the letter  s  is placed before one of these ta#m consonants:  ', p, o, ,, ], or  ;, they follow the rules of the su4uN class.
               
su4uN   ta#m  
s' NO4O ' NO2O
sp ñO4O p ñO2O
V nO4O o nO2O
| mO4O , mO2O
s] lO4O ] lO2O
s; vO4O ; vO2O
               
   In the above combinations the  s  is silent.  It only serves to indicate that the following consonant is to be considered a su4uN consonant.  (Notice how  s  is joined to  o  and   ,  e.g.  s  +    o   V   s  +   ,    | ;  The combination  s  +  ]  is often written  s^.  s  +   p  is often written  sP .)

    The syllable  0k  is pronounced kha4a.  Look at the following syllables and read them aloud.

               
0k l= 4n g0u gl 46
kha4a sO4O thyy4 khe4e se4e thu4u

g9qhk,u1kg9a[sq;0kp    
                   
   Here are some su4uN syllables with mày eêk:

ho#N kha#a su#u vii# pha#a
                    
            WHAT TONE DO THEY HAVE?  Answer!

(Click here to refer to the Lao Tones Chart.)

            Rule:  A syllable which begins with a su4uN consonant and has a mày eêk has high-mid tone.

            (The use of the mày eêk is the same for all three classes of consonants.   It always indicates high-mid tone.)

            PRACTICE READING THE FOLLOWING SYLLABLES:

                    
  l=felugs]nv'16jgmy'8aj'
  g9qhk0PoVa'lnlv'lk,dhko
  8voc]']k;dyo16jIkhovksko
  16jglaomk'lk,clowm
  vksko9uoc-[s]kp
  ohv'lk;,adlvoVa'ln
               
   The mày thóo indicates high falling tone for the kaaN/Middle Class and ta#m/Low Class consonants:  e.g.
               
8qho [hk mhkp ohv'
tòn bàa thàay nO1ON
               
   For the su4uN/High class, however, it indicates low falling tone.  e.g.
                
0hvp z6h
khO3Oy phu3u
               
   Rule:  su4uN + mày thóo has low falling tone.

            PRACTICE READING THE FOLLOWING SYLLABLES:

                    (Remember:   (1)  Any consonant + mày eêk has high-mid tone

                                         (2)   kaaN or ta#m + mày thóo has high falling tone

                                         (3)   su4uN + mày thóo has low falling tone)

All of the syllables in the above exercises were "Smooth or Live."   That is, they ended in a long vowel or a final m, n, N, l, r, y, w.  The following exercises will deal with "Checked or Dead" syllables: Syllables ending in -p, -t, -k, glottal stop (sudden closure of the glottis).  The reason for this is that the air flow of these syllables is checked or stopped, i.e. made "dead" by the lips (-p), the tip/blade of the tongue (-t), the back of the tongue (-k), or closure of the glottis (?).
             
   Look at the following and read them aloud.

   There are two more su4uN rules to learn, those for su4uN + short vowel and su4uN + short vowel + stop.  Look at the following and read them aloud.
