The transcription of the Georgian letter g is g.
g is pronounced almost like English gin go.

Recordings:
 

When pronouncing the consonant g, the back part of the tongue, touching the end of the hard palate, covers the space between the wisdom teeth and partially the molars and goes upwards, in the direction of the soft palate. The soft palate  goes downwards to the upper part of the tongue and by active participation of these two prgans occlusion-plosion is created.

The letter written or typed in this way is called gani.

It is traced out with one movement of the hand and is written between the three lines: movement of the hand begins  below the upper middle line, goes upwards drawing a small circle from left to right at the upper middle line, and ends at the lower middle line, having a question-mark like shape, continues to the right and ends with drawing an ellipse between thge lower and lower middle lines.
