/n/ is a nasal sound. To make an /n/ sound, raise the front of your tongue to above your top teeth, and make the air travel through your nose, instead of your mouth. If you block the air with the back of your tongue, you will make a different sound /ŋ/ so make sure you use the front of your tongue. ESL learners sometimes have trouble with hearing and saying the difference between these two sounds.
Like /m/, /n/ is made by blocking the mouth, but /n/ is made by blocking the mouth with the tongue, not with the lips, so that air is forced out through the nose. /n/ is voiced. Like /m/ it is impossible to shout /n/ sound. Let’s look at some examples. Word-initial /n/: nine, niece, knees, noise, knob. Word-medial: penny, loner, honey, funny, many. And then, word-final: skin, thin, fan, lawn, soon. Now let’s look at some /n/ sounds that are in words that are in sentences. Nora has nine new napkins. A penny saved is a penny earned. Nancy knows buns and honey. If you’d like some more practice, look below.
