How to Pronounce the /n/ Sound

/n/ is a consonant sound in the English language.

As you can see in picture (b), this sound is also nasal because it is produced from the nose. In order to produce it, we must first put the tip of the tongue on the roof of the mouth. This will help block the air coming out of the mouth. Then, we start vibrating our vocal cords. So, this sound is voiced and you can see that the circle in the throat is red. Since the air cannot come out of the mouth, it travels up to the nose. Note that the uvula is participating in the production of this sound.
As you can see in the picture (a), the lips and the teeth are slightly parted. So, we cannot produce this sound if we keep our mouths closed.
For more clarification, we have provided you with a picture showing exactly where the tip of the tongue and the roof of the mouth make contact. In picture (c), the highlighted part indicates that you have to put the tip of your tongue there. Below, you can find letters that represent this sound:
