1. In Lao, a "yes" or "no" answer to a question is often formed by repeating the verb or adjective.  In answering in the negative, the high-mid-tone negative particle /bO#O/ precedes the verb or adjective.

For example,

,ad[=	ma#k bOO	Do you like it?
,ad	ma#k	Yes.
[=j,ad	bO#O ma#k	No.
s;ko[=	wa4an bOO	Is it sweet?
s;ko	wa4an	Yes.

2. "yu#u" X16j?   has several uses.  In this lesson it follows a verb or adjective.  It affirms the meaning of the verb or adjective, but does not modify it in any way.  Compare the two answers.

For example,

Ihvo[=	hO1On bOO	Is it hot?
Ihvo16j	hO1On yu#u	Yes. (At least it isn't cold)
Ihvo16j	hO1On yu#u	Yes, it is.

3. "na4aw" XVk;?   "cold" and "yen" Xg1ao?,  "cold" have overlapping meaning.  "yen" is used for something which is cool or cold to the touch.   "na4aw" XVk;?  may be used to describe the weather.  "na4aw" is also may be used to describe the weather.  "na4aw" is also used to say, "I'm cold, he's cold."

For example,

vkdkfVk;	?aaka3at na4aw	It's (the weather) cold.
vkskogpao	?aaha4an yen	The food's cold.
0hvpVk;	khO3y na4aw	I'm cold.
,ngpao	my2y yen	My hands are cold.

Incorrect: ?aaha4an na4aw. na4aw is the bodily or internalized cold that you experience or feel;   yen   is relative temperature, something that can be tested by a touch of the hand or tongue.

4. Note the word order when "si" Xly?  and "bO#O" X[=j? - the negative - occur together.

For example,

lywx	si pay	I'll go.
[=jwx	bO#O pay	I don't go.
ly[=jwx	si bO#O pay	I won't go.
