1. The pronouns khanɔ̀ɔy ຂ້ານ້ອຍ   'I',  thāan ທ່ານ    'you', and phǝ̄n ເພິ່ນ 'he, she' are called deferential pronouns.  They are used in formal settings to show respect to someone of higher position or greater age.  phǝ̄n ເພິ່ນ   should be used when speaking of one's parents.  There are also other ways to address those of greater age.

2. One uses khanɔ̀ɔy ຊ້ານ້ອຍ   at the end of a sentence when speaking to a superior. 

ລາວສິໄປ ຂ້ານ້ອຍ

láaw si pay khanɔ̀ɔy

He is going, sir.

3. náaŋ ນາງ   and thàaw ທ້າວ    are used for persons of school age and above, up to middle age.  Other terms are used for older people.  náaŋ ນາງ   and thàaw ທ້າວ      may be used in place of the pronouns 'you', 'he', and 'she'.  

ນາງສິໄປໄສ

náaŋ si pay sǎy

Where are you (female) going?

4.    ñáa ຍາ   is a term of respect used before such words as phɔ̄ɔ ພໍ່    and mε̄ε ແມ່  and personal names.

ຍາພໍ່	ñáa phɔ̄ɔ	honored father
ຍາແມ່	ñáa mε̄ε	honored mother
ຍາແສງແກ້ວ	ñáa sε̌εŋ daaw	honored Sengdao
ຍາພໍ່ຂ້ອຍສິໄປ ໃນເມືອງ	ñáa phɔ̄ɔ khɔ̂y si pay náy mýaŋ	honored father is going to town.

Although  ñáa phɔ̄ɔ ຍາພໍ່   and ñáa mε̄ε ຍາແມ່     literally mean 'honorable father' and 'honorable mother', they are often used in addressing persons who are not one's parents but who are about the same age as one's parents.  Like náaŋ ນາງ   and thàaw ທ້າວ,   they can be used as pronouns.

ຍາພໍ່ສິໄປໄສ	ñáa phɔ̄ɔ si pay sǎy	Where are you (father) going?
When addressing one's father or a man of one's father's age.
ຍາພໍ່ຂ້ອຍສິໄປ	ñáa phɔ̄ɔ khɔ̂y si pay	My honorable father is going
ໃນເມືອງ	náy mýaŋ	to town.
