I want to get a German name. Please help me. I hope there can be the pronunciation of n i in it.

This German name can be Nina.

the letter n is pronounced as /n/ in German. When pronounced, the lips and teeth are slightly opened, the tip of the tongue is stuck with teeth, the soft palate droops, and air is pumped through the nasal cavity to vibrate the vocal cords. For example,

NIna

nennen is called

kennen knows

brennen is burning

I hope I can help you solve your doubts.
