graceful
娜 centers on graceful, elegant movement or appearance, often associated with feminine poise.
娜 combines 女 (woman) with 那, which likely contributes the sound. The character is used to express feminine gracefulness.
A woman 女 beside 那, which looks like flowing lines, suggests a graceful, elegant figure.
For ダ, imagine a graceful dancer: dancer -> ダ, and her movements are as elegant as 娜.
