The top yellow field, which is 4⁄5 of the height of the flag, indicates the space under the sun, inhabited by the people of the Chuvash Republic.

The tree of life, which occupies 3⁄5 of the width of the flag, is a sign made on the basis of Old Chuvash runic writing, whose silhouette resembles a revered oak tree of Chuvash, powerful and durable, resistant to natural storms.

In addition, the Tree of Life, as a single organism, personifies the unity of the people living in the territory of the Chuvash Republic.

The emblem "Three suns", consisting of a three-fold repetitive ancient solar sign (an eight-pointed star), symbolizes the sunlight that gives life and protects well-being.

Threefold repetition of the star that overshadows the main emblem of the flag - "The Tree of Life" means the Chuvash folk concept "Pulna, Pur, Pulatpar" ("Were, Is, We Shall") and is its graphic expression.
