How to make this sound:

Video Text:

The ll sound. To make this sound, we use the very tip of the tongue, and we press that to the roof of the mouth. This is different from the nn, N sound in which we use the forward part of the top of the tongue to touch the mouth. In the L, ll, we're acutally using the very tip, which means the tongue has to curve up to touch. Ll, ll. Because the tongue is curving like that, that means this part of the tongue is acutally touching the back part of the front teeth. But where the pressure happens is where the tip of the tongue reaches up to touch the roof of the mouth. Ll, ll, ll. The rest of the mouth stays relaxed. Sample words: last, parallel, limber. Sample sentence: Last fall, we flew to California.
