1. Note the difference in Lao between the following two questions. 

For example,

g9qhk,koe.z	ca@w ma#a na#m pha%y	Who did you come with?
g9qhk,koespa'	ca@w ma#a na#m Na%G	How did you come?

2. The sentences pay sa%y ma#a wxwl,k and khi&i Na%G ma#a 0ujspa',k         have a similar structure.  ma#a ,k  is a secondary verb showing direction toward the speaker.
3. he&t kaan gIafdko    means 'to work at one's profession'.  pay kaan wxdko   means 'to go to one's office'.  he&t wi@ak gIaf;Pd    means 'to work, do a task'.
