As is mentioned above, preverbs in Georgian denote not only direction but also orientation -- the position of the speakers (participants of conversation -- the first and the second persons) -- whether motion is directed to the place or from the place where the speakers are.

Georgian preverbs make up two groups:orientation "here" and orientation "there".

The preverb mo- expresses orientation "here" and the preverb "mi-" -- orientation "there".
Other preverbs express the orientation "here" by adding the preverb mo-:

a-dis - a-mo-dis
a-dis - a-mo-dis

Ca-dis - Ca-mo-dis
cha-dis - cha-mo-dis etc.

Simple preverbs -- formed without adding the preverb mo- -- express the orientation "there".

The orientation "here" implies the motion directed to the place where either the first or the second person is present.
The orientation "there" implies the motion directed to the place where  neither the first nor the second person is present.

Orientation "here/hither" is used when the motion is directed:

• From the third person to the first person; e. g., is mo-dis chemtan s/he is coming to me.
• From the third person to the second person; e. g., is mo-dis shentan s/he is coming to you.
• From the second person to the first person; e. g., shen mo-di-xar chemtan you are coming to me.
• From the first person   to the second person; e. g., me mo-v-di-var shentan I am coming to you.
• From the first person to the third person if the second person  is meant to be together with the third person; e. g., memo-v-di-var mastan (Mziastan) I am coming to him/her (to Mzia) (the second person to whom I tell this is also with Mzia).
• From the  second person to the third person if the the first person is meant to be together with the third person; e. g., shen mo-di-xar mastan (Mziastan) You are coming to him/her (to Mzia) (the first person, I, who  tells this is also with Mzia).
• From the third person (A) to the third person (B) if either the first or the second persons is meant to be together with the third person (B); e. g. Mzia mo-di-s Datostan (either the first or the second persons is meant to be together with Dato)

• From the first person to the third person (if the second person is not understood as being together with the third person)
• From the second person to the third person (if the first person is not understood as being together with the third person)
• From the third person (A) to the third person (B) if neither the first nor the second person is understood as being together with the third person (B).
